Xorg.conf is missing from /etc/X11. I tried to recreate it, but got this error: "Number of created screens does not match number of detected devices. Configuration failed."
what to do?
1. Do you really need it?
2. How you tried to recreate it?
3. You can write this by hand (if you have simple configuration)
Code:
Section "Screen"
Identifier "Default Screen"
Device "Default Video Card"
DefaultDepth 24
EndSection
Section "Device"
Identifier "Default Video Card"
Driver "nvidia" # use this for nVidia proprietary driver
Driver "nv" # or this for nVidia open source drivers
Driver "fglrx" # or this for ATI proprietary driver
Driver "radeon" # or this for Radeon open source drivers
# others I don't known
EndSection
video card is with ATI chip, HD4850.
Xorg.0.log contains no errors.
what config file? the missing one?
perhaps I should elaborate on '1.'
Debian works fine with my monitor in 1600x1200. but when I connect TV (1920x1080 on hdmi), monitor displays only part of picture.
problem seems to be, one screen has higher X resolution and the other Y.
I've played with xrandr and believe that, to solve the problem, 'virtual screen' in xorg.conf should be increased.
also, I thought having xorg.conf might decrease slightly bootup time.
The output from lspci would be more helpful.
Yes, but if I could see it I could understand what driver is being used and perhaps get other useful information.
You said you wrote and /etc/X11/xorg.conf
I guess it would be best to post the Xorg log file for the cases both with and without your custom xorg.conf.
Evo2.
lspci:
01:00.0 VGA compatible controller: ATI Technologies Inc RV770 [Radeon HD 4850]
no, I didn't write xorg.conf. I tried 'automatic recreate' with: Xorg -configure
Maybe I'm missing something, but you don't seem to have explained what problem you are now having? According to the Xorg log file you posted, X seems to be starting up and running fine, correct?
I didn't think that setting a Virtual screen size was necessary any more with KMS. KMS can dynamically grab as much memory as it needs for your screen real estate.
However, if you want to set the Virtual value, I don't see any reason you can't create an xorg.conf file with with 'Xorg -configure' and then edit the Screen section to put in the Virtual value.
d'uh
I can't recreate it with 'xorg -configure' because it reports error:
"Number of created screens does not match number of detected devices. Configuration failed."
If 'Xorg -configure' reports that error, there's something wrong with your installation of Xorg. You can, however, still manually create an xorg.conf file with just a Screen section, and put the Virtual line in there.
