Summary: random XRandR failures (i2c related?)
Product: DRI
Version: unspecified
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
AssignedTo: dri-devel at lists.freedesktop.org
ReportedBy: aelschuring at hotmail.com
A few weeks ago, X started displaying weird errors during normal use. These
range from simple output resets to application crashes due to X BadAlloc
responses. In detail, this is what I see happening:
- output blink. Usually the screen goes dark for about a second. When the
screen returns, I see either:
- display position getting cancelled (xrandr --pos 0x0) on my left screen
when this happens I can usually get it back to the correct position via the
xrandr command line tool, but sometimes that triggers a WM crash
- display rotation getting cancelled (xrandr --rotate normal) on the right
screen. When this happens:
- quodlibet (python-gtk app) crashing with BadAlloc (serial 255 error_code 11
request_code 53 minor_code 0). It will keep crashing like this until I restart
X
- whatever other app I had running on the right screen has disappeared as
well
- window manager (e17) crashing. It can recover succesfully, though
- when I re-enable screen rotation, the display gets completely garbled
I have started seeing this happen with 2.6.35-rc3 (was running 2.6.34-rc6
before that), and with 2.6.35.1 this happens a lot less frequently (from once a
day to twice in a week).
