Alt + Ctrl + F# X screens blank

Legolas327 · 12-26-2009, 04:50 PM

I am carrying this thread over from another once I narrowed my troubles down to the xorg.conf file. If I use a simple non-duel monitor xorg.conf file then all is well. With a duel monitor xorg.cong file my duel screens work just fine, I just cant see my alt+ctrl+F# sessions.

When using duel monitors my Alt+Ctrl+F# screens are blank. No cursor, nothing! I have been operating in duel screen mode for years but for some reason have this problem in Ubuntu 9.10. I am using the nvidia-settings built xorg.conf file and tried all sort of suggestions from others postings to no avail. If I default back to a single monitor then my Alt +Ctrl+F# X sessions work fine..

Linux Serenity 2.6.31-16-generic #53-Ubuntu SMP Tue Dec 8 04:02:15 UTC 2009 x86_64 GNU/Linux

I am posting my xorg.conf file hoping someone can see what my problem is.

hi

1) assuming you have xorg 1.6 or higher....you should not have any mention of mouse or kb in your xorg.

these are now handled by fdi files and hal....so after backing up...edit and remove all mentions of input devices and then reboot to see if that fixes it

If fail then

mv /etc/X11/xorg.conf-old /etc/X11/xorg.conf
su xxxx
(where xxxx is your local username)
startx

then go to (2)

2) I do not have such hw...single for me....but
http://manual.sidux.com/en/hw-dev-mon-en.htm#xrandr

suggests you look at
http://www.sorgonet.com/linux/nv-online/

and create a script to run to fix your xorg.conf.....after backing up of course

Taking advice I removed any reference to keyboard or mouse. It didn't change anything.
Then using xrandr and cvt I determined what each screen would prefer for resolutions and generated a new xorg.conf file:

No change in blank screens when Alt+Ctrl+F#. Keep in mind that the duel monitors work just fine, but changing to an Alt+Ctrl+F# give blank screens?

When using the sudo xinit -- :2 command I get a terminal but get these errors which I don't have a clue about or even know if they are relevant to my issue:
