Screen resolution

[Nicker]

I'm using Kubuntu 7.10 and I'm having trouble setting the right screen resolution. I think.

The settings used to be in /etc/X11/xorg.conf, but now I don't see them anymore. It's good to have a graphical interface to set up the screen (1280 x 1024 in my case). But...

Those settings are only valid for the user account. Before I actually log in, the screen resolution is larger than it should be. OK, the login dialog is still visible, but it's off center and the screen blinks after I log in (and the resolution changes).

Is there a way I can fix that?

Re: Screen resolution

Could you post your xorg.conf?

Re: Screen resolution

In your section entitled "Screen", change it to look like the following:
[quote]Section "Screen"
Identifier "Default Screen"
Device "ATI Technologies Inc RV280 [Radeon 9200 SE]"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24

Re: Screen resolution

Thanks. I'd thought I'd better not mess with xorg.conf, since it was now done through a GUI. More so, because there were no resolution entries and I thought they were moved somewhere else.

But now I changed it, anyway. Nothing is different, though. Maybe it's just my perception. Hm. :-| After the install I had to reduce the resolution from 1400x1050 to 1280x1024 (using Monitor & Display of System Settings GUI). But the initial login screen looked much the same as it does now: the dialog is off center (down and to the right), just as it would be if the resolution was, say 1400x1050 (plausibly speaking), so I thought that goes to faulty auto-detection. Could be just a feature, though. 120px is not as big a deal.

Thanks anyway.

I guess not. Screenshot at http://debianadmin.com/copper/displa...album=82&pos=0 looks OK. Mine doesn't.

Re: Screen resolution

Another thing I found out: if I log out, the login dialog is centered as it should be. But on a (re)boot, I get the off-center one and the resolution is, I guess, 1400x1050.

Re: Screen resolution

OK, I've been holding this back until I knew for certain the above suggestion wouldn't work (for experimental purposes because I don't own an ATI card and had the same experience with my Nvidia card). Try using Envy to install the ATI driver; just download the latest .deb package, and, if you're on Gutsy, click it and Gdebi will install it for you. If not, open Konsole and 'cd' to the directory you downloaded the package to (if I downloaded it to my Desktop, I would use the command "cd /home/username/Desktop"; replace username with your username). Then, enter the command

sudo dpkg -i envy* && sudo apt-get install -f

That should install it for you. You can use either a GUI (Graphical User Interface; type envy -g or click it in KMenu -> System -> Envy) or command line tool (type envy -t). That should fix your resolution problem . . .

Edit: Actually, I just did some experimentation; instead of 'cd'ing to the directory and then installing it, try this modified command:

sudo dpkg -i */envy* && sudo apt-get install -f
