Fixed screen resolution and frequency - running on Fedora 8
Hi, I'm relatively new to Linux, so please go easy with the technical jargon. My screen has been locked into 1024x768 and at 61 Hz for some obscure reason. I tried to change the resolution of the monitor through system -> administration -> display (running on GNOME) and then rebooted, but the problem still persists. As for the frequency, it doesn't give me any other option other than 61 Hz (this is kind of problematic, as the screen looks really fuzzy). It seems to me that the graphics drivers are not set properly. How do I fix these problems? Thanks in advance.

It sounds like the VESA driver was installed. Tell us the specs on your monitor and video card, and we can get you pointed in the right direction.
To jump in with both feet, open up /etc/X11/xorg.conf The sections we will want to look at are similar to the following: Code:
Section "Monitor" Post the equivalent sections from your file. |
Ok so my graphic card is "Radeon RV100 QY [Radeon 7000/VE]" and my monitor is a 19" Dell Ultrasharp 1900FP. Here is the content of xorg.conf:
Code:
# Xorg configuration created by system-config-display |
the first thing to try is to replace "vesa" with "ati" (in the Device section). You can also try "radeon" if that driver is on your system. I also think the HorizSync maximum looks too low. (Check the specs on your monitor.)
You have no modes specified for the default depth of 24 bits. I would simply change 16 to 24 in the 2nd Display subsection, and delete the first one. If it won't run at the desired resolution, then try a modeline. Use gtf to generate it, and then put it in xorg.conf following my example. to edit xorg.conf, open a terminal, "su" to root, and enter "nano /etc/X11/xorg.conf". If you don't like nano, substitute gedit or whatever else you like. |
Hi again,
Apparently there's an issue with the graphics drivers. I can't choose anything other than vesa - setting "ati" or "radeon" prompts me that those drivers weren't found. I've check whether the driver files were on my machine and they were quite strangely. Would you have an idea of what's going on? Thanks in advance. |
Here's what I have (partial)
in /usr/lib/xorg/modules/drivers: Quote:
Code:
Section "Device" |
I'm having a similar problem. When I go to System->Prefs->System Hardware->Scren Res and click on either the Res or Refresh Rate, nothing shows up on the drop down.
Code:
My xorg.conf contents: I'm using a Dell Inspiron E1505 laptop with a: 256MB ATI MOBILITY™ RADEON® X1400 HyperMemory™ Video Card and a 15.4 inch UltraSharp™ Wide Screen SXGA+ Display with TrueLife™ monitor |

Normally, it's not good to jump into existing threads with a different problem. In this case, there is obviously SOME overlap. You can manually add a Monitor section using mine as an example (Use the specs for your hardware). You can also try running "xorgconfig" (In a terminal, just enter that one word--without the quotes. For the complete spec on xorg.conf, do "man xorg.conf" |
Had the thread not been so similar to mine or been so old that I would've majorly bumped it, I would have made my own, but people often end up getting mad at not using the Search function of Message Boards, so I figured I'd avoid that.
And I'm running Fedora 8, and since the Fedora crew took xorgconfig out of the command list, I can't run it. Also, is there an easy place to find out what my hardware is capable of for me to put it into xorg.conf? |
pixellany, i dont have a problem per se, but i do want to update my video driver and enhance my video experience. I got Ubuntu 7.10 and I got an Intel 82852/855GM Integrated Graphics Device. How do I update this integreted video card?
Also, how can I further tweak my video settings optimally? Thanks!!! |
