Summary: r600: Garbled screen after resuming from suspend (KMS) Product: DRI Version: DRI CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: direx@betriebsdirektor.de
Created an attachment (id=36970) --> (https://bugs.freedesktop.org/attachment.cgi?id=36970) system log
Using mesa-git, libdrm-git and xf86-video-ati-git I always get a garbled screen (including framebuffer console) after resume. I took a screenshot, but obviously it looks normal.
Video card: Radeon HD3870 Kernel: Linux-git (2.6.35-rc4+), KMS enabled by default
There is no crash or lockup, it's just sort of impossible to read anything on the screen after resuming.

--- Comment #1 from Jerome Glisse glisse@freedesktop.org 2010-07-12 13:11:55 PDT --- Can you take picture of the screen (no need for high res pic, just something good enough so we can see the issue). Also could you boot and suspend with drm.debug=15 option and attach system log with that option (after suspend/resume cycle)

I'm using archlinux, with last mesa-git, ati-git,libdrm-git.

What about pm-utils? Do you use it? If so, try version 1.3.0 which recognizes KMS.

--- Comment #6 from Alexandre Derumier aderumier@odiso.com 2010-07-13 04:43:38 PDT --- i'm using pm-utils 1.4 (no problem with drm-radeon-testing around 20 june)
i'll try to dig around pm-utils, i see they are many video quirks in
usr/lib/pm-utils/video-quirks/

Sorry for the late reply. I cannot find the commit which broke it, however this is still an issue.
I figured out that using xrandr after resuming fixes the garbled screen (setting a different resolution and restoring the original one afterwards).

Still an issue with recent kernel ?
Yes. The exact same thing is still happening to me on 2.6.38-rc4 and xf86-video-ati git.
As I already mentioned the garbled screen issue goes away when using xrandr after resume. I personally fixed this for me by executing the following *dirty* quirk-script on resume:
export DISPLAY=:0 export XAUTHORITY="/home/$USER/.Xauthority" xrandr --output DVI-0 --mode 1920x1080 xrandr --output DVI-0 --mode 1680x1050
But obviously this cannot be a permanent solution.

Can you dump your regs before and after calling xrandr? using radeonreg available here (http://cgit.freedesktop.org/~airlied/radeontool/)
(as root after resume): radeonreg regs all > broken.regs (run xrandr) radeonreg regs all > fixed.regs

Are you using an analog or digital connection for the monitor?
I am only using digital connections.
The card has three ports: DVI-0: My primary monitor (through DVI) DVI-1: My AV receiver (using the DVI2HDMI adaptor that came with the card), usually turned off DIN: Not used (radeon.tv=0).
And I just noticed a very interesting thing: The TV connected to my AV receiver (DVI-1) works just fine after resuming - only the primary screen on DVI-0 is garbled.
