Kernel 2.6.35 and ati video card problem?

csslayer · 2010-08-04 06:44:13

I'm using kde 4.4.95 and kernel 2.6.34 and it works quite well here (with quite a lot kwin effect enabled).

But after I tried 2.6.35, actually it works but all effect will be suffered with blinking...

I tried mesa from git but no help (even worse), I checked libdrm and found there isn't relative update from 2.4.21.

What do you mean by blinking? I am using 2.6.32-lts with KMS enabled and the xf86-video-ati-git driver installed and I occasionally get a second where the monitor turns black and goes back to normal again. However, when I tried 2.6.34 with KMS disabled, I would get very rapid flashes on the screen (I couldn't enable KMS on 2.6.34 because of issues with my monitor not receiving the signal).

Can you elaborate more on what the problem is?

Same here, kde 4.5 + kernel 2.6.35 with kms enabled and windows are flickering. If i disable kms flickering stops. With kernel 2.6.34 no flickering with or without kms.

ps. from what i remember kde 4.4+kernel 2.6.35-rc5 didnt produce flickering.

Thanks for your information

Can you confirm that kwin freeze while change kwin settings while kms enabled? (only ati card and open source driver and kms)

Anyone else notice a huge performance drop? With kernel 2.6.34 I get round about 1000 fps in glxgears and now with the kernel 2.6.35 I only get 50 fps (I know glxgears is not a benchmark, but the desktop effects are laggy too). I have an ATI X700 and the latest radeon driver from the testing repo.

I think that is cause by vertical synchronize.
glxgear's fps will approximately the same as the monitor refresh rate.

But I don't know how to disable it though...

flamelab · 2010-08-04 12:41:38

Try

export vblank_mode=0

in /etc/profile

Lothium · 2010-08-04 13:08:03

Thanks for your advice, but nothing has changed. Glxgears is around 50 to 60 frames and the effects are choppy...

It's probably related to radeon dynpm feature (it's causing some problems):

I have same problem, KDE 4.4.95, Kernel 2.6.35, glxgears 50-60 fps and graphics performance very low, with active effect is desktop unusable.

abraxas88 · 2010-08-04 21:17:25

Same problem here and if I try with

export vblank_mode=0

in /etc/profile

it solves only a part of the problem.

jarryson · 2010-08-05 09:42:23

samilier problem here, the glxgears fps become 59 now, witch is 1700+ with 2.6.34.

i am using gnome + compiz, the blink problem also happened here, but not very common.

Video card: X700 mobility

A lot of problem are releated to this bugs:

Please help if you can.

poorguy · 2010-08-11 15:27:13

i had the same problem but upgrading to 2.6.35.1 solved my problem.

Zapp! · 2010-08-11 16:23:58

I have an Ati Radeon HD 3200 and have the same problems mentioned earlier.
I noted an error that might me causing this:

cat /var/log/everything.log | grep mesa
Aug 11 18:13:48 zapp kernel: You have old & broken userspace please consider updating mesa

Maybe mesa needs to be compiled against kernel 2.6.35, I'll try that later.

Didn't work, I'm back to kernel 2.6.34 for now.

Should I create a bug report? And if so, against kernel26 or mesa?

schen · 2010-08-11 22:04:13

Ok, same issue with me, although I'm still using 2.6.34. This may be a separate issue.

However, I put export vblank_mode=1 into /etc/profile, and I noticed when running glxgears, this showed up:

ATTENTION: default value of option vblank_mode overridden by environment.
ATTENTION: option value of option vblank_mode ignored.
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.

After I update to kernel 2.6.35.1 and mesa-git and xf86-video-ati-git, everything works like a charm.
local/ati-dri 7.9.git20100812-1
Mesa DRI drivers for AMD/ATI Radeon
local/libgl 7.9.git20100812-1
Mesa 3-D graphics library and DRI software rasterizer
local/mesa 7.9.git20100812-1
Mesa 3-D graphics libraries and include files
local/xf86-video-ati 6.13.99.git20100812-1

local/kernel26 2.6.35.1-1 (base)
The Linux Kernel and modules
local/kernel26-headers 2.6.35.1-1
Header files and scripts for building modules for kernel26

P.S. I use special PKGBUILD to build package that different from AUR only for keep the same package name with offical package.

cookiecaper · 2010-08-12 05:57:10

Rebuilding the dri toolchain with -git versions as above resolved the problem for me. Oddly, I did not get the problem initially after installing kernel 2.6.35.1. Maybe another recent update has exposed the problem. Someone should push these updates to stable when 2.6.35.1 goes in.

cookiecaper · 2010-08-12 19:32:30

Anyone make an ArchLinux bug for this yet?

TigTex · 2010-08-12 22:30:44

I had a smiliar problem with my ati 9250se (old old old). It seems that with 2.6.35 vsync is always on (see glxgears...), but I also had vsync ON forced in xbmc: everything was flickering. Once i disabled vsync on xbmc, everything is back to normal AND vsync is on.
If possible, try to disable vsync and see if it helps you.

semog · 2010-08-12 23:21:24

hi same here i have a ati radeon xpress x1100 and flickering hapens when use effects so anyone have a soltion ? with 2.6.34 i have flickering too so maybe is not kernel i dont know
on kde 4.4.5 this dont happen so maybe a kde 4.5 bug?

tomk · 2010-08-12 23:26:43

cookiecaper - this is not an Arch bug. If rebuilding the userspace packages from git fixes the problem, that indicates that the issue has been fixed upstream. Arch is not going to provide *-git packages, so anyone who doesn't want to build their own just has to wait for the next upstream releases.

cookiecaper · 2010-08-13 03:51:05

Some packages I have installed currently don't have real version numbers, just revision numbers or build dates. See mplayer or ffmpeg (off the top of my head). I guess they're probably exceptions since they almost never issue releases and just tell everyone to use SVN, though.
