Boot log from 3.11.0-18 with debug enabled
I've got Ubuntu Saucy on a desktop with Intel G41 chipset (Asus
P5G41M LE/CSM). It exibits weird behaviour. Kernel: Linux kolya
3.11.0-18-generic.
When I boot system up, login into X session and run xrands I get this:
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 connected 1920x1080+0+0 (normal left inverted right x axis y
axis) 531mm x 299mm
1920x1080 60.0*+
1280x1024 75.0 60.0
1152x864 75.0
1024x768 75.1 60.0
800x600 75.0 60.3
640x480 75.0 60.0
720x400 70.1
DP1 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
In this state I can switch to a text mode console and it works fine.
Then I suspend/resume machine and run xrandr again with following result:
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected 1920x1080+0+0 (normal left inverted right x axis y
axis) 0mm x 0mm
DP1 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
1920x1080 (0x47) 148.5MHz
h: width 1920 start 2008 end 2052 total 2200 skew 0 clock 67.5KHz
v: height 1080 start 1084 end 1089 total 1125 clock 60.0Hz
Note, that all screens are in disconnected state. Fortunately I still
see my desktop.
But unfortunately when I switch to a text console my monitor goes
into power saving mode and doesn't return from it even if I type on
keyboard. Also if I leave my X session (i.e. logout) my monitor goes
into sleep on all virtual terminals and I have to reboot the box.
I've tried to 'redetect' screens in my X session but it doesn't help
to fix the issue. Disconnecting/reconnecting screen doesn't help as
well. Reboot helps.
I'll attach dmesg output with drm.debug=0xe as suggested in the mailing list.
I've tried booting drm-intel-nightly on same machine but it hangs during boot
saying (sometimes, sometimes I get black screen) something about softlock. It
is probably graphics related since it does boot with 'nomodeset', but I would
guess that is not interesting for this particular bug.
I would be happy to provide any additional information or to test things.
Thanks!
