[Bug 127008] Re: Alternate install of Tribe-4 corrupts video display when installing packages (affected hardware includes Santa Rosa)

2007-10-17 Thread unggnu
Ok, I have tested it with the daily build of the 16th. It losses the ability to 
save any resolution in xorg.conf (there is no resolution saved) but thanks to 
xrandr I guess I get the correct native resolution and it works fine out of the 
box. Since all the Intel cards are shipped with the new Intel driver and if no 
other app has problems with an xorg.conf without a resolution it would be fine.
Btw. this was the first time that the usplash doesn't break up before X starts. 
Maybe that has something to do with it too.

Same problem here! With the installation of the daily build of October
15, with the Alternate CD of Gutsy.

During the second half of the installation, the screen becomes completely 
unreadable.

[Bug 127008] Re: Alternate install of Tribe-4 corrupts video display when installing packages (affected hardware includes Santa Rosa)

2007-10-15 Thread Bryce Harrington
Soren confirmed through IRC that this solves the issue adequately.

The regression risk for this bug is low.  The code is invoked only for
cards where autodetection failed, and attempts a second autodetection.
This change skips this second autodetection for Intel cards; at least
some proportion of Intel cards (maybe all) suffer from screen corruption
during installation, making it extremely hard to complete installation.
The effect is that users will have to manually provide some extra
information during installation.

So the worst case regression here is that laptop users with Intel
graphics that fail the primary autodetection, but would normally be
autodetected by xprobe.sh, will now instead receive a prompt for
resolution.  However, I suspect this is going to be a vanishingly small
number of cases.  In any case, the harm of the regression is small,
whereas the harm of not including the fix is much higher.

davmor2, what you're experiencing clearly is not this bug, but something
unrelated.  Please report separately.

Soren, we need confirmation and more detailed info from you that you
were testing a Daily ISO, and not just gutsy -beta.  I'm assuming you
were testing -beta, since I'm quite confident this fix should resolve

2007-10-10 Thread Bryce Harrington
Since the bug is confirmed fixed for the others that reported it,
there's something different about your system.

Basically, we need to know if either a) your system somehow fails with
the same bug with ddcprobe as with xprobe.sh, or b) for whatever reason
on your system xprobe.sh gets called instead of ddcprobe.  See my
comment 30 for how to get into a testable environment.

The pci id 8086:3582 is 82852/855GM Integrated Graphics Device.  I see
it is a device that used to be blacklisted to use -i810 rather than
-intel.  So I agree albert's question about whether -intel is being used
or perhaps i810 is relevant.  If -intel is being used, maybe this simply
means we need to re-blacklist your laptop to stay with i810.  I recall
we had troubles with getting -intel on it at the sprint in london.

2007-10-10 Thread Soren Hansen
I did a little digging. xresprobe calls ddcprobe.sh. If that doesn't
give it a valid resolution, it calls xprobe.sh, too. Indeed, on my
system, ddcprobe (not ddcprobe.sh) says edidfail, so ddcprobe.sh just
returns with no output, and hence xresprobe calls xprobe.sh and smashes
my screen.

At the sprint in July we discovered that the new xrandr magic had hugely
better effect if I was using the -intel driver. I'd be sad to see it go,
but I'd also like to get this bug fixed :)

2007-10-10 Thread Bryce Harrington
Soren,

Ah, well an edidfail could explain it.  This doesn't leave us too many
options, but possibly the best of the worst is to simply skip xprobe.sh
entirely for Intel laptops.  I suspect this may result in various other
issues, but all much less severe than a hang during installation.

Here is a debdiff and .deb for this.  Can you test this to verify it
fixes the hang issue, using the approach from comment 30?

http://people.ubuntu.com/~bryce/Testing/xresprobe/

As to the edidfail issue, bug 94994 already describes that.  My
suspicion is that there are multiple versions of EDID, and ddcprobe only
supports one version.  However, that's something that I'm going to have
to leave til later to sort out.

I used a slightly different patch to prevent doing the x probe. I enabled the 
ddc probe when the driver is intel.
$RES gets set and prevents the x probe.
I made a new CD and the installation went OK. The screen was readable during 
the complete installation, no more colored blocks.

After installation the system rebooted normally and X was started with
the correct resolution (still using the patched xserver-xorg-core from
bug 144956)

2007-09-27 Thread Bryce Harrington
Awesome, that looks like an acceptable solution to me.

I did a bit more experimentation, and I found that after installation
has completed (even before rebooting), the issue cannot be reproduced
using the steps I outlined.  So it is only occurring during a very
specific point of time, after /target is mounted, but before
installation has completed.  I did a `modprobe vga16fb fbcon` to turn on
the installation environment's framebuffer, but that was not sufficient,
so there is something more unique about that environment than just the
vga16fb.  I wonder if packages are in an inconsistent state or
something...  (Maybe there's  a mismatch between what's in memory and
what's on disk?)

Anyway, since I couldn't find anything more enlightening that way, I
think your patch is going to be the best way to go.  I'll roll it out
directly.  Good work!

2007-09-27 Thread albert
Bryce, I have done the check with only the forced ddcprobe successfully.
I just thought leaving your patch in would be a safety belt, in case there is 
any hardware where ddcprobe cannot set $RES.
I must admit I have no idea how likely that would be.

2007-09-27 Thread Bryce Harrington
Rolla, sorry yes that's correct.

albert, thanks for the confirm!  Actually I think if we're confident
ddcprobe will catch it for this case, we should rely only on that.  My
patch could have side effects on other hardware, and so if we don't
think we need it, we should leave it out and avoid those effects.  We
can always add it later if needed.

One thing I've wondered is other laptops with different gfx chipsets may
be experiencing problems like these (but with different symptoms.)  So,
it'd be good to keep an eye out for any bugs that are occurring for non-
intel laptops doing the alternate text install and appearing late in the
install process; we could expand this patch to include those cases as
well.

Anyway, I've posted the source package for upload here, will shoot for getting 
it out tomorrow:

It looks like most of the affected systems are laptops.
My screen is reported as LVDS. Bryce, what do xresprobe and xrandr say about 
your display?
Could there be a difference between how LVDS and other types of displays are 
treated?
I tried to test my system with external monitor, but unfortunately I cannot 
switch off the internal display and xresprobe still reported lvds/lcd.

On my 965gm desktop (detected as 82G965), which is connected to a crt
through a kvm, xresprobe reports it as a crt display.  I'll test it
with a directly connected lcd as well...

Btw, I've posted a .deb for a fix for bug 144956 at
http://people.ubuntu.com/~bryce/Testing/xorg-server/.  From what I can
tell, it is not related to this bug as it's issue only appeared after
Tribe 5, but might be worth testing in case I am wrong.

Since it sounds like this might be a laptop-only issue, could those of
you experiencing this issue run the 'laptop-detect' command right after
the question about language support?  By design, it should be returning
0 if running on a laptop, 1 if not, and 2 if there's an error.  Perhaps
for whatever reason, it's screwing up?

2007-09-26 Thread albert
xresprobe seems to work different for laptop and crt/lcd. For laptop it
seems to do DDC and xprobe, for lcd/crt only DDC.

If I run xresprobe with XRESPROBE_DEBUG=1 set, I get:
laptop: yes; ddc:

(and a lot of empty lines)

I think the x probe is only done if $RES is not set? Would that make
your patch for bug 144956 more relevant?

2007-09-26 Thread albert
During installation:
chroot target, then laptop-detect returns nothing
laptop-detect -v returns: we're a laptop (dmidecode returns notebook)

I tested the patch for bug 144956. The colored blocks still appear. However, 
after reboot my laptop came up with 1280x800 as it should. Previously it came 
up with 1024x768.
(I rebuilt the patch for amd64 and customized the beta CD)

After installation and with debug enabled, xresprobe still shows it
probes X. Same output as above, except for the now correct resolution of
1280x800.

I guess if the ddc probe in xresprobe would find the right resolution for my 
laptop, the x probe would not be needed and the problem would be solved. I am 
not sure if the ddc probe in xresprobe is the same as ddcprobe, but this is 
what sudo ddcprobe gives (after 1st reboot):

[Bug 127008] Re: Alternate install of Tribe-4 corrupts video display when installing packages (affected hardware includes Santa Rosa)

2007-09-26 Thread Bryce Harrington
Aha, I figured out how to reproduce it on my desktop:

Boot with the alternate CD, go through the installation until it has
reformatted the drive and started installing things to /target.  Next
`chroot /target`, then wait until the file
/usr/share/xresprobe/xprobe.sh is present, and then invoke it:

 /usr/share/xresprobe/xprobe.sh laptop

Boom, colored squares.

Essentially what this script is doing, is running

 /usr/bin/Xorg :67 -ac -probeonly -logfile logfile -config
config

using the xorg.conf from /usr/share/xresprobe/xorg.conf, with intel
specified as the driver.

So... one solution could be to disable running xprobe.sh for driver
intel.  I've attached a patch for this.

However, I think this risks ending up with an improperly configured
graphics system.  Let me experiment more and see if I can come up with a
better solution.

As nobody seems to have a clever idea how to test the suggested patch, I
used brute force to do it:

- patched and build xserver-xorg-core (for amd64, in pbuilder)
- modified the tribe 5 cd to include the new .deb

Unfortunately I got the colored blocks again during installation.

After the installation was complete and the system was rebooted, I
verified the right xserver-xorg-core was installed (ubuntu7) and the
changelog included my change entry.

Here is a deb including the aforementioned patch, could someone test
this?

http://people.ubuntu.com/~bryce/Testing/bug127008/xserver-xorg-core-
dbg_1.3.0.0.dfsg-12ubuntu7~ppa1_i386.deb

Since this occurs during installation, I'm not sure how easy this is
going to be to test...  Possibly switch to a terminal early in the
installer, install the deb, and then continue the installation?  If
someone knows of a better procedure for testing, please share it here.

The description of the patch is, Screen size changing should leave FB
alone when X is inactive.  I'm just making a wild guess that perhaps at
some point during installation, one of the packages does a screen size
change before X has been made active, which then affects the framebuffer
which for this hardware results in the screen corruption described in
this bug.

2007-09-21 Thread albert
I have done a series of installations, trying to find the offending
package.

First run the installation up to the question about language support,
then switch to tty2 and use apt-install/apt-setup to manually install
packages.

Test 1
install and setup xresprobe: no problem, then install intel: colored blocks 
(setup intel was not needed to get the blocks)

Test 2
install and setup intel: no problem, then install and setup xresprobe: still no 
problem

Test 3
install and setup xresprobe: no problem, then install and setup 
xserver-xorg-core (from tribe 5 cd): still no problem, then install and setup 
intel: still no problem.

I have done test 1 and 3 earlier this week, with the same result.

So I think I would need to use a set of smaller X packages, with less
dependencies, to test the patch correctly.

[Bug 127008] Re: Alternate install of Tribe-4 corrupts video display when installing packages

2007-09-17 Thread Bryce Harrington
Looking through all the duplicates for this bug, it appears pretty much
everyone's hardware is amd64 and gm965.  The issues appears to have all
been noticed in August, around tribe3/tribe4.

Looking at the xresprobe changelog, this appears to coincide with a
change made by Matthew Garrett to add support for the Intel driver.
This didn't *cause* the bug, but probably just revealed it; prior to
this, xresprobe wouldn't be able to deal with -intel.  However, my guess
is that the root issue is in the intel driver, not in xresprobe itself;
xresprobe simply triggers it.

Can anyone reproduce the issue after installation by running 'xresprobe
intel'?  If so, could you then try running 'xrandr --output TV --off'
and then 'xresprobe intel' and see if that makes it go away?

There are reports upstream with this chipset that the TV out detection
can confuse the resolution detection algorithms.  If this is the case
here, then we need to ensure tv out is disabled for this card.  See
https://bugs.freedesktop.org/show_bug.cgi?id=11366 for the patch.  It
can also be turned off in xorg.conf:

Section Monitor
   Identifier TVOutput
   Option Disable true
EndSection

Then in the Device section add:

  Option monitor-TV TVOutput

If it can be determined that TV-out is not the cause of this issue, then
we should probably report it upstream; I could not find other reports of
this behavior in the xorg or debian bug trackers.

2007-09-17 Thread albert
In my system the TV output is already disabled (without the above lines in 
xorg.conf). Running xresprobe intel does not give the colored blocks.
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1280
VGA disconnected (normal left inverted right)
LVDS connected 1280x800+0+0 (normal left inverted right) 331mm x 207mm
   1280x800   59.9*+   60.0

   800x60060.3  
   640x48059.9  
TV disconnected (normal left inverted right)

I did find something in the logfiles: the installation uses framebuffer
and loads modules fbcon and vga16fb (+ some depending modules). My
installed system does not use these modules.

When I do the installation without any additional boot option, I get the 
colored blocks
when I do the installation with boot option vga=771 or fb=false, I don't get 
the colored blocks.
Could this mean the problem is caused by using framebuffer with the intel 
driver?

I also found a way to reproduce the problem manually: I don't answer the 
question about language support in the installation but switch to tty2. When I 
just install xresprobe and xserver-xorg-video-intel manually, the colored 
blocks show (no boot-option).
Could I retrieve more information by doing this manual install with some 
special options?

This also seems to happen on both i386 and amd64. Likely this is related
to vbetool segfaulting instead of properly POSTing the card on resume
from suspend. (And hence the backlight not coming back on 965GM.)

2007-09-17 Thread Kevin Wang
the issue happends on i386 version on santa rosa as well and I didn't
see this issue with Weybridge platform.

I agree with Albert, the TV out is already disable, seems the issue
related to framebuffer, when I do the installation with vga setting
640x480, everything is OK.
