[Bug 313701] Re: [KM400]black screen after logout
Ok, short answer: yes and no.
Full story:
I've updated my copy of the openchrome source to svn revision 817. I ran
'./configure --enable-debug --prefix=/usr' and then proceeded with make.
I uninstalled the xserver-xorg-video-openchrome package and installed
the self-built openchrome driver with checkinstall. Then the machine was
rebooted.
Things that worked before still worked, so I could log in to my desktop
with GDM. I suspended the machine, resumed it and logged out. I got the,
to me, familiar black screen instead of the GDM login screen. The
corresponding Xorg.0.log file is attached as Xorg.0.log.before.
Then it hit me that I did not, as requested, put in the Option
"ModeSwitch" "new" in the xorg.conf file. I went to a console and logged
in, added the necessary Option line to the Device section and did a
'sudo restart gdm'. Amazingly, life got back into my dead login screen:
the backlight turned on and I could see, well, colors. I've attached a
picture I took with my camera of the screen so show what I mean
(gdm_restart.jpg). The corresponding log file is attached as
Xorg.0.log.after. So, this Option does make a big difference.
Unfortunately the display is unreadable.
I then rebooted the machine to report on this issue here, but
unfortunately I could log in at all anymore, since the login screen was
garbled and mostly black. I made a picture of this as well
(gdm_boot.jpg). I couldn't even get to a console anymore, and had to
reboot in single mode to comment out the Option "ModeSwitch" "new" line
in xorg.conf. After a reboot, everything is back to the way they were.
Thank you for your continuing effort!
Robert
