I installed Slackware v10 yesterday and I'm trying to get the resolution to the 1024x768 that my monitor supports, but X seems hellbent on staying at 640x480.

I've tried Xorg's config command and also gone to /etc/X11/xorg.conf to try and change it, but that isn't working. Also, a friend of mine was telling me about a combination of keys (ctrl/alt/+, I think?) to cycle through resolutions, but I haven't ever gotten that to work for me, even before Slack switched to this "Xorg" stuff.


Any help will be greatly appreciated; thanks y'all.

What video card are you using? And what does your screen section say in xorg.conf? You can adjust xorg.conf to use the resolution you want as long as your video card is being properly supported.
If you log into Gnome and use the display manager are any other resolutions available?

I can't find the specs for the video card on this machine; whatever it is, I know it should be able to handle the conservative settings I'm trying to give it. This computer is by no means powerful--I got it for free because it's hardly worth anything--but it was running much better resolution when I got it (originally with WindowsME).

In Gnome, the display manager's drop down menu doesn't list any other options. In the xorg.conf file...

Subsection "Display"
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubsection


...and then it also has the options for other depths. Is this where I'm supposed to be looking? It seems to be the only area of the file to mention resolution.



Thanks again,

Jason

try doing a lspci -v to see a verbose listing of your system devices. You should see what type of graphics card you have and then you can go from there to get xorg.conf setup right. Did you try running xorgconfig? The video card and memory are important, as are the refresh rates for the monitor. Once you have that information right everything should work our for you.

It's much better now. Thank you very much for your help.

As Vincent_Vega mentioned, HorizSync and VertRefresh in the "Monitor" section of xorg.conf are also important.
