[gentoo-user] cursor problem with compositing, KDE, nVidia

2010-07-25 Thread »Q«
I've googled a little, but searching for problems with KDE and nVidia
still turns up so many horrors from the KDE 4.0 days that I can't find
my current problem in the haystack.

After updating to KDE 4.4.4, my cursor disappeared.  Occasionally, I'd
see it briefly, but mostly it was invisible.  I turned off compositing,
and everything is ok.

But I am spoiled by some of the compositing features, esp. the quick
ways to see all open windows, so I want it back.

Complete solutions are of course welcome :)  but I'd be very happy with
any pointers about what settings to consider for xorg (1.7.6) or
nvidia-drivers (195.36.24) or KDE.

(I may be slow to respond, very busy this week.)

I like the idea of pythons, as they swallow the prey whole its much less

Must be a coincidence, didnt update the MBR after installing grub and

Well, lots of good information previously posted. Here's a
few more tidbits. When ATI video get's older, there's
always good opensource solutions to keep using it. Nvidia,
sometimes you toss in garbage can, or use vesa or
get lucky? Dunno, as I personally avoid Nvidia; other 
insist on Nvidia. kinda a religious thing with some.

For example, I have a fanless ATI video card 
ATI Technologies Inc RV710 [Radeon HD 4350]
where I'm currently using ati-drivers. Sweet enough
for most video gaming, silent and power efficient.
I just got this card, but have not set it up yet:
HIS Radeon HD 5550 Low Profile Video Card,
also fanless.

There is new support, open source, in the kernel for ATI video,
Look here under graphics:
http://kernelnewbies.org/LinuxChanges

and here:
http://www.x.org/wiki/radeonhd

So I use ati-drivers on the newer ati video cards, then
switch to open source drivers, as the hardware matures or 
support, via open sources, becomes robust for a given generation
of ATI video product. One thing to remember; It's kind of 
difficult to change the video card on a laptop

ymmv;hth,

Yes, -f does seem to be the right option. It's been ages since I used ext3 and 
I have no real way to do a test, so I played safe. And the man page could be a 
little more descriptive too, -f left me with more questions than answers.

I'm using KDE 4 on Gentoo, and I want to add a few items to the "K"
(application launcher) menu.
I thought the control center was the thing to use, and the online help
manual says it should exist
on the "K" menu, or as the program "kcontrol".

It doesn't, and the list of files for "kcontrol" contains *no* files of that
name, and only one directory
(under HTML) of that name.

So how to I run the darned thing?

Suspend should work.  3D however is too slow.

You'd be better of using the proprietary driver, especially since on a 
notebook you want to have increased battery life; the open source driver 
doesn't provide good power management.

Open Source (x11-drivers/xf86-video-ati) and Close Source drivers
(x11-drivers/ati-drivers) do both work with suspend2ram.


From this mailing list (my post) 06/24/2010 10:22 AM +0200, Subject "Re:
[gentoo-user] ATI  RV710/730" in regards to ATI only:
-
ATI: 3D is very good - a must for gaming, 2D is SLOW! (thou they did
something about that  with 10.6 - experience differs for users - its
said that window management is fast now, but video still has tearing
effect [also my exp.])
Latest driver (10.6) work with xorg-server-1.7.x only and kernel module
has problems with >=2.6.34 (exp. differ).

Xorg: 3D is basic and very slow but works (the newer the driver/server
the better, development is VERY fast), 2D is a dream (very fast, no
tearing with video)!
Driver is released with Xorg - so work always with newest Xorg, kernel
module is in-kernel - work always with newest kernel :) Driver supports
both KMS and user space MS.
-

So... for buying... if u need only 2D (and basic 3d) -> intel.

If you want to play games: nvidia or ati/amd...

The OSS-driver 4 ATI is MUCH more mature and ATI/AMD gives out
documentation and also develops - work is going very well, but will take
time for 3d to catch up. Still for OSS -> ATI.

The closed source drivers of nvidia are much better (very fast match new
kernels and Xorg releases) than the closed source drivers of ati (they
are like a year behind kernel/xorg releases)! So if you plan on being
always on closed source drivers (because you game often or use
3D-software for modeling or so) then x11-drivers/nvidia-drivers works
better. The nvidia driver also offers hardware accelerated HD-video
playback (1080p H264 -> only 10% CPU, rest in GPU).

Daniel

You don't need to invalidate the journal or mount ext2, just use -f if
memory serves, be sure the partition is unmounted and that will force a

KH, I think that this may not be related to a fs error as such.

Yes, pulling the plug may have caused fs corruption.  However, more likely is 
that pulling the plug did not allow you to do something that you should have 
done after you finished upgrading to grub-0.97-r9.  The latest installation of 
grub asks you to reinstall in the MBR and point its root to wherever your 
/boot is.  GRUB's fs and its drivers may have changed and therefore the old 
boot loader code is looking for files that no longer exist.

So you'll probably be alright again if you boot with a fresh systemrescue 
LiveCD and run grub and then root (hd) and setup (hd0) before you quit and 
reboot.

If that doesn't work then you most likely have a fs problem.

HTH.

Hi All,

I was using the gspca_zc3xx module with kernel 2.6.32-r7 without any

My webcam is : A4 tech PK-635M and I am using wxcam (my own ebuild)
Also I have tried with kopete and cheese but result is same.

I have tried with ubuntu 10.04 (kernel 2.6.32.xxx) and it is working as
good. I guess there is a bug in the 2.6.34.xx series?

When I run the wxcam with command line I am getting some errors and

Hi,

I ran on the two partitions e2fsck /dev/sde3 as well as fsck.ext3
/dev/sde3 . Yes, it only took some seconds.
 

It's been a long time since I used ext3 so some of this might be wrong.

An fsck that takes a few seconds is using the journal, which might not uncover
deeper corruption. You should try disabling the journal (I couldn't find the
way to do that though), but this will also work:

Boot of a LiveCD, mount your root partition somewhere using type "ext2" and
fsck it. This will invalidate the journal but that's OK, it gets recreated on
the next proper boot. Let the fsck finish - it will take a while on a large
fs.

When done, reboot as normal and see if the machine boots up properly.


   


And I would stand guard to make sure housekeeping doesn't come around.

It's been a long time since I used ext3 so some of this might be wrong.

An fsck that takes a few seconds is using the journal, which might not uncover 
deeper corruption. You should try disabling the journal (I couldn't find the 
way to do that though), but this will also work:

Boot of a LiveCD, mount your root partition somewhere using type "ext2" and 
fsck it. This will invalidate the journal but that's OK, it gets recreated on 
the next proper boot. Let the fsck finish - it will take a while on a large 
fs.

When done, reboot as normal and see if the machine boots up properly.
