Slackware Linux screen resolution problem?
I am using Slackware 10.1 GNU/Linux? OS and quite happy with that. Though I am an advance user, I am having a problem with that!
I want to set the screen resolution to 1152 X 864 with 75Hz Monitor VF that works well with dual boot Windows 2000 Pro. Currently Slackware shows, 800 x 600, 1024 x 768 and 1280 x 1024 (60 Hz). I tried with XorgConfig file but in vain.
So, what do you think?
Two possibilities come to mind:
While I can't speak specifically to Slackware, I can suggest a tool to use: Sax2. This is an open source tool from Suse (now Novell) that is included in Suse/Novell Linux, plus a few others (Yoper comes to mind). Get the source from Suse, compile and try Sax2. Here's a link.
Just to be a bit more clear, Sax2 is an xfree86 configuration utility. It still has its quirks, but my colleagues have found that when it's unware of a supported resolution it's easy to add that to the configuration and test it out. One great advantage is that it tests the changes you wish to make before committing them. A very handy feature when tweaking refresh rates. It helps keep you from "breaking" the config!
Also, you can edit the /etc/X11/xorg.conf by hand at the Section "Screen". Take note of the DefaultDepth [8-32] and Subsection "Display" which will help you figure out your default startup color depth - and just change the Modes to "1152x864" and restart X and you're done. The assumption here is that your monitor will support that resolution else you may end up with a virtual screen (which can be nice sometimes).
You could also just try adding:
Modeline "1152x864" 107.48 1152 1208 1336 1584 864 864 867 904
last in your "Monitor" section.
Your BIOS might not list that resolution though.
Finally, as with any other configuration tweaking, please be sure to back up your xorg.conf before you mess around with it.
