[Bug 1430888] Re: DRI_PRIME with radeon/intel windows do not draw

[Timo Aaltonen]

I'm going to assume this is fixed with mesa 12.0.6 and if you enable
DRI3 or uninstall xserver-xorg-video-intel (which lets it fall back  on
-modeset which uses DRI3)

[Luigi R.]

Same for me on Ubuntu 16.0.1. I get a black screen by using DRI_PRIME=1
glxgears but the frame is highen the Intel card.

Is it normal that xrandr --listproviders returns 2 providers for the
AMD/ATI card?

Providers: number : 3

Don't know if it can help, but enabling DRI3 solves the problem for me.
Just added this to /usr/share/X11/xorg.conf.d/20-intel.conf :

Section "Device"
Identifier  "Card0"
Driver  "Intel"
Option  "DRI" "3"
EndSection

ad restarted X

[Bug 1430888] Re: DRI_PRIME with radeon/intel windows do not draw

[munbi]

Same problem here: Dell Latitude E6540 with Intel HD4000 + AMD Radeon HD8790M 
(OLAND), Ubuntu 16.04 updated.
Some OpenGL programs do not refresh the windows and shows only artifacts from 
background when using DRI_PRIME=1 to lunch (e.g. with kicad pcbnew)

Followed comment #11 suggestion and tried latest Oibaf PPA (
https://launchpad.net/~oibaf/+archive/ubuntu/graphics-
drivers?field.series_filter=xenial ) with:

- mesa 12.1~git1608230730.96ea75~gd~x 
- xserver-xorg-video-ati 1:7.7.99+git1608230731.b08670~gd~x
- xserver-xorg-video-intel 2:2.99.917+git1608121931.c8fc7f~gd~x
- libdrm 2.4.70+git1608210630.b214b0~gd~x
- llvm-toolchain-3.9 1:3.9~+rc2-1~exp1~gd~x

with same result, so updating to mesa 12.1 seems does not solve the
problem.

Tell me if you need any info or log file, this is a really critical bug
and, for now, I can't use my dedicated GPU on Ubuntu.

[Bug 1430888] Re: DRI_PRIME with radeon/intel windows do not draw

[Alessandro Viprati]

Similar problem in Ubuntu 16.04.1 (Unity), with AMD APU (AMD A4-7210 APU
with AMD Radeon R3 Graphics "MULLINS") + AMD GPU (AMD Radeon R5 M330) on
a Lenovo Yoga 500-14ACL.

Everytime I launch a 3D game application with DRI_PRIME=1, the system
hangs and returns to the lightdm login screen.

I also tried to use a xubuntu session (installing xubuntu-core package)
with xfwm or compton, but the problem persists.

st/dri: Clear drawable texture_mask in dri2_invalidate_drawable

This makes sure that dri_set_tex_buffer2 -> dri_drawable_validate_att
will re-create the front left attachment buffer after the drawable got
invalidated.

Fixes window contents not updating until the window is resized when
using DRI2 PRIME.

I see this too with Steam, only for me the log string is " reporting 6 8 17 
141". Ctrl-Win-D workaround seems to work. 
Any updates on this in the meantime?

[Bug 1430888] Re: DRI_PRIME with radeon/intel windows do not draw

[Wolfgang Wallner]

In my case, starting steam causes the text 'reporting 9 5 33 271' to be added 
to /var/log/Xorg.0.log three times.
It's always printed twice in a row and again a few seconds later.
For example these are two starts of steam:

[ 17002.853] reporting 9 5 33 271
[ 17002.878] reporting 9 5 33 271
[ 17006.628] reporting 9 5 33 271
[ 17021.267] reporting 9 5 33 271
[ 17021.297] reporting 9 5 33 271
[ 17025.236] reporting 9 5 33 271

But this does happen with and without DRI_PRIME=1, so I don't know if it
is related to this bug.

Additional note regarding compositing:

*) The problem happens regardless if compositing is enabled or disabled.
*) Enabling compositing fixes the problem (as far as I can tell always).

If I start with compositing on, I need to toggle it for the problem to be gone.
If I start with compositing off, I just need to enable it.

-- Something that is done when compositing is turned on fixes the
problem.

(I use KDE and use Shift+Alt+F12 to enable/disable compositing)

This bug is already present in 14.10.

My system is a HP Pavilion laptop with a muxless Intel/AMD combination
(Intel Sandybridge HD graphics and AMD Radeon HD6770).

A Workaround that works most of the time is to press Win+D again and again to 
switch between desktop and game application.
After a few iterations the problem is usually gone: once a game (or steam) 
starts drawing, everything works fine.

[Simon K]

Could you please check your /var/log/Xorg.0.log to see if it contains the 
following Text:
reporting 7 6 5 37

For me it repeats very often if I've started an 3D program with DRI_PRIME where 
this Error appears.
This Message will repeat very often like:

[  1033.178] reporting 7 6 5 37
[  1033.280] reporting 7 6 5 37
[  1046.783] reporting 7 6 5 37

The problem is also independent of multi-monitor configurations.
I use a dual monitor setup, and it happens regardless if both monitors are 
activated or just one of them.

[Bug 1430888] Re: DRI_PRIME with radeon/intel windows do not draw

[Wolfgang Wallner]

I tried to reproduce the problem with glxgears.
It can happen, but it is harder to reproduce than with steam.
For steam it happens every time, for glxgears it only happened twice out of ~15 
tries.

But when it happens in glxgears, no reporting 9 5 33 271 lines are
added to Xorg.0.log, so I think these are two different issues.

The compositing-enable trick also works for glx_gears.

As far as I can tell the problem only happens with certain programs.
I think it depends on whether or not OpenGL is used for drawing.
For me it happens for

*) Steam
*) Games (both Steam and others like e.g. supertuxkart)
*) glxgears

It does not happen for typical office programs that use GUI toolkits
like Qt or GTK, e.g. okular, gedit, etc.

According to [1] Steam uses a custom toolkit called VGUI, which is also uses by 
their Source engine.
Thus I would guess that it is also drawn using OpenGL.
