Thread: Changing screen resolution manually

    Changing screen resolution manually

    HiHo!

    I've Suse 8.0 installed with KDE running.
    During setup I choosed for my monitor "VESA 1280x1024" and everything went fine....after some work at KDE I realized that the screen was somewhat blurred.
    Because I thought it was a driver problem I downloaded the latest nvidia drivers and installed them .... the next time I started X the nvidia logo came up so I suppose I installed them correct.
    Unfortunately the screen shape hasn't improved. So I tried to change the resolution to 1024x768 which works fine at Window2000 .... but - and that's my problem - I can't start sax2!! Everytime I try to start it, linux hangs and I have to do a "Ctrl-Alt-Del" to reboot (it's the only thing my computer responds to).

    Is there a way to change the monitor to "VESA 1024x768" and the screen resolution to "1024x768" manually in some sort of config files?
    Or is there a way to fix this sax2 problem?

    Thnx in advance...

    not sure but more info is probably needed:
    -do you see a penguin in the upper left at boot.
    -card name/model #
    -
    Code:
    grep -i modeline /etc/X11/XF86Config
    post the output of that.

    Dude, I got a SuSE box as well (8.0 rocks) and what you gotta do is jsut edit your /etc/X11/XF86Config file as root, of course. There will be a section with the resolutions that are available for each bitdepth. If what you want isnt in there add it (pretty straightforwared sysntax, dont worry its easy). If its all there do a CTL+ALT+PLUSKEY or CTL+ALT+MINUXKEY on the numeric keypad to scroll back and forth thru all the available resolutions.

    Hi!
    I don't see a penguin ... it's the SuseLogo ... but I think we both mean the same. 8)
    It's all working fine...no boot problems and no problem at working in linux, except that the screen doesn't look good enough.

    I have a Elsa Gladiac card (GeForce2MX400) and as I said the newest driver installed. I'll try to reinstall these drivers, maybe it'll help.

    Ah, and grep gives me the following:

    Hope this helps. I think it's some sort of resolution or frequenzy problem. CTRL - ALT - +/- works, but when I decrease the resolution this way the screen flickers like hell.
    Man, if just could get into sax *>

    Anyway, thnx so far for any help.

    Update:

    I saw some errors in the XF86 log ... something with GLX and so on - and because I'm a bit lazy and don't want to fool around with this, I reinstalled Suse8.0 and voila, now it works fine
    It was a fresh install so it would have taken me longer to fix the error than to reinstall the whole system.

    Anyway, thnx for the help. At least I have learned about a new command (grep) which I think can be very usefull.

    Actually I forgot to mention this (yeah I am a dick) but in SuSE's manual it states that you need to go into runlevel 3 to run sax2. I tried it in X and it puked out (had to tap on the reset button) and when I init 3'ed the system, it let me run it and rerunlevel 5.

    I suppose I should have mentioned that :(

    The yast module "monitor & graphic card" (let's hope it's called that way, because I have a german system and I translated it) didn't work either, and now after reinstalling it works fine, even in runlevel 5
    I only tried sax2 because the yast module only made my system freeze.
    Anyway thnx for the info...
