i have an intermittent issue with "ATI Mobility Radeon X1300" on an up-to-date archlinux laptop running gnome-shell.. all's well until rendering breaks, sometimes after many hours/days use.. there's no real sign of a repeatable action and nothing reported in logs.. X continues to run and the mouse cursor is active, and even changes to represent the screen content..
the closest i can get to a repeatable action is an almost certain freeze using gimp with strenuous brush activity using the clone tool on an average size image.
if i restart gdm i still have no mouse/keyboard interaction with onscreen although gdm dress is displayed.. if i killall -HUP gnome-shell in the running session the window content (without decorations) briefly displays but when it settles only the background appears
if i switch to the VT and back to X then window content with border decorations is displayed instead of background image, but still no interaction
i can't launch any X applications from VT or ssh, or use another WM to replace.
`DISPLAY=:0 openbox --replace` results in:
"Invalid MIT-MAGIC-COOKIE-1 keyOpenbox-Message: Failed to open the display from the DISPLAY environment variable."
however, if i kill gdm, and create an xinitrc for openbox i can start an Xsession with keybd/mouse interaction, so i guess there's definitely something up with 3d (offscreen?) rendering
from within the openbox session: running glxgears just shows an empty black box.. all other glx demos are the same empty boxes.. when i'm logged in to this openbox xsession i can launch xapps via `DISPLAY=:0 foobar` variable.. so this bug i'm encountering must do something to interrupt the ability to draw new windows?
i can only get a working 3D X session by unloading/reloading kernel drivers.. radeon/drm/ttm/drm_kms_helper..
here's the very basic script i'm using to unload drivers so i can start X with 3D.. --- #!/bin/bash
# unbind kms fb before unloading modules.. echo 0 > /sys/class/vtconsole/vtcon1/bind sleep 1
# unload kernel modules rmmod drm_kms_helper ttm radeon drm sleep 1
# reload kernel modules modprobe radeon ---
