Description:
With the graphical chipset Xpress 200M Series (Radeon Xpress 1150), booting with KMS gives you sometimes, as soon as Xorg boots, a screen with many vertical colored stripes. You cannot Alt+Sys+K or do anything. With ati-dri 7.8.2-3, libgl 7.8.2-3 xf86-video-ati 6.13.2-1 i can use the "nomodeset" option to disable KMS and boot correctly. With the new versions, xorg refuses to boot : Backtrace: 0: /usr/bin/X (xorg_backtrace+0x28) [0x49f1a8] 1: /usr/bin/X (0x400000+0x60239) [0x460239] 2: /lib/libpthread.so.0 (0x7fbee425d000+0xf1c0) [0x7fbee426c1c0] 3: /usr/lib/xorg/modules/extensions/libglx.so (0x7fbee2069000+0x38868) [0x7fbee20a1868] 4: /usr/bin/X (FreeClientResources+0xee) [0x44a2ee] 5: /usr/bin/X (FreeAllResources+0x49) [0x44a3a9] 6: /usr/bin/X (0x400000+0x21305) [0x421305] 7: /lib/libc.so.6 (__libc_start_main+0xfd) [0x7fbee31e2c4d] 8: /usr/bin/X (0x400000+0x20e79) [0x420e79] Segmentation fault at address 0x75 Fatal server error: Caught signal 11 (Segmentation fault). Server aborting Additional info: * package version(s) : ati-dri 7.9-1 libgl 7.9-1 xf86-video-ati 6.13.2-2 i tried also with the last kernel and xorg packages : kernel26 2.6.36.1-3 xorg-server 1.9.2-2 libdrm 2.4.22-1 but these don't seem to give any problems. Steps to reproduce : just boot your system with KMS enabled, you will have vertical colored lines very often. Without KMS, X refuses to boot. |

i have vertical stripes when i use KMS, and cannot start X without KMS. I am forced to ignore any updates of these packages and stay to the older versions quoted in the topic.
However, I can upgrade any other packages such as kernel26 or xorg-server.
However, by disabling dri usage it works better. Despite of having to use 'nomodeset' again, i can start X without any problems. I have no more 3d acceleration (100FPS instead of 1000FPS with glxgears) but at least, it works.
By the way, if i disable "dri" and use no kernel options (no "nomodeset") i see the vertical stripes at boot, only for 5 seconds, before having kdm displayed. Then, i have the same results.
If I start for example KDE Desktop Effects, i will see again the vertical stripes for 5 seconds...and return to kdm ! :)
- kernel 2.6.37-5
- xorg-server 1.9.4-1
- libdrm 2.4.23-1
- mesa 7.10.0.git20110206-2
- ati-dri 7.10.0.git20110206-2
- xf86-video-ati 6.14.0-1
- libgl 7.10.0.git20110206-2
To summarize the situation :
- 3D isn't working at all (if you execute for example extremetuxracer the screen freezes with the same colored stripes, and it never works,
- the 2D situation is the same. You need to test several times (around 3 or 4), to see vertical stripes after booting.
So i'm currently forced :
- to disable DRI,
- to disable KMS by adding 'nomodeset' to boot options.
So, what should we do ? Should we follow this bug here, or should i open an upstream bug to xorg developers ?
Regards,
Use KMS because it's the only recommended mode nowadays. Test with DRI disabled to locate if the striped are caused by 3D rendering. Bring it upstream to the proper Kernel or Xorg part. I can't help out here. So either provide an upstream report to follow or I will soon close this again.
So, the major bug is today that you still cannot use DRI with this chipset (Radeon Xpress 1150) on my Dell Inspiron 1501, or any 3d function. Any "3d program" makes your display totally crashes with the vertical stripes, with major consequences (you're forced to shutdown the machine, loss of KDE configuration after rebooting...). Can you confirm that, or is 3D working on your laptop ?
Well, i can produce a bug to Mesa and/or kernel developers for that. Do you want me to link any bug report i could make there to the bug i reported here ?
Regards,
maybe you can try to replace kdm with gdm/lxdm for testing. it may also be a bug in kdm if doesn't happen in the desktop once you are logged in.
