Can't get high resolution in Slackware
 

Hi,
im the distro im running is Slackware 10.0. My monitor is able to run 1400x1050 easiley in Windows and other linux distro's. I can't get any higher then 640x480 though in slackware.
my graphics card is Nvidia MX440-8x 64mb.

I have updated my drivers and still nothing works. I have also tried to "force it" to higher resolution by editing my xorg.conf and xorg.conf-vesa files. but when i start KDE it goes back to 640-480.

here's a copy of my xorg.conf file
here is also a copy of my xorg.conf -vesa file

is there any other files that im supposed to mess with? im new to this because it's never been a problem in other distros. any help is greatly appreciated

Have a look at /var/log/Xorg.0.log to see why it does
what it does?

ok, i checked out the log file and i'm getting a bunch of "hsync out of range" errors.
I dont know what the hsync rate should be on my monitor. I also dont have the manual that came with it either. How could i find out what my Hsync is in Windows?

hurray,
i looked on the back of my monitor and it told me what the Hsync range is
i put it in the xorg.conf file and Viola!!

thanks Tinkster

Congratulations mate :)

I am having a similar problem. I have a monitor that is capable of 1280x1024 (Dell FP1900), but I can only get 640x480. I used kxconfig to set my hsync to 30-80kHz and my vrefresh to 56-76Hz and my resolution to 1280x1024. I am using the generic vesa for my graphics card. I don't see a /var/log/Xorg.0.log, but I do see an XFree86.0.log. In it I see this error: 'Not using mode "1280x1024/74Hz" (No mode of this name)'. It is repeated for 800x600 and then it apparently defaults to 640x480 with something about attempting a refresh rate of 73Hz and then "Using shadow framebuffer".

I am confused kxconfig forced me to pick 74Hz (the specs for the monitor recommend 75, but I wasn't given the option). Any ideas, how I get around this.

Thanks much--

I don't know what kxconfig is, and you didn't list your distro - but apparently you're using XFree - so you can modify the file XF86Config (or XF86Config-4, depending on distro) and add in the correct specs for your monitor for HorizSync and VertRefresh. (don't guess at these - find the specs online if you don't have the manual - wrong values can damage h/w)

then make sure you have "1280x1024" as the first option in the display subsection for your default depth.

Sorry. The distribution is Slackware 9.1. kxconfig seems to be a KDE interface to xconfig.

I got the figures that I entered into kxconfig from the Dell support site; so they should be accurate for the monitor.

How the monitor and screen sections of my /etc/X11/XF86Config look like right now is listed below.

Thanks--
