Resolution "fixed"at 640x480

[transke]

Hi

Fedora Core 2 and resolution setting.

I have problem in Anaconda Installer and Fedora KDE and Gnome. have resolution 640x480 when I try to change to higer resolution eg. 800 or 1024x768 still is 640x480 but desktop is larger.

I tried to run Knoppix first and everything seemed all right.

My computer: Motherboard: MSI k7n2g-ILSR, 512MB RAM,
ATI Radeon 7000, Seagate 120Gb S-ATA, Monitor: Eizo FlexScan L550


When booting from the CD, Anaconda recognizes the monitor as L550. When probing for it later with ddcprobe it does not detect any monitor at all.

In Knoppix the Xfree86Config file contains this:

Here is the contents of the curent xorg.config file on my system. I have tried to change these parameters to look more like those in knoppix but nothing changes. Maybe I am doing something wrong?

I have not installed any drivers from nVidia because I do not know how to do that(I am used to Windows) and the drivers I have is only for windows. But I tried Mandrake awhile ago on the same system but with another monitor and I did not have this problem then. So I assume it is something with the monitor.

If anybody out there would use their time to give me some help with this I would very much appreciate it...Please tell me if you need more or information.

Ctrl + Alt + +/- dont work.

Look up your monitor vertical and horizontal sync rates and change them in the monitor section.
Your monitor looks like it's set at a bare minimum setting.

I'm not familiar enough with XF86Config files to recognize any problems in yours without mine in front of me to compare.
If you are using an nvidia based video card, you should be able to use the 'nv' driver that usually comes with linux.
Installing nVidia's drivers is very easy. Go download the latest driver from www.nvidia.com. You'll have to click on the download drivers link at the top of their page, then select your OS (linux) and architecture (probably x86, or IA32 is what nvidia calls it, I think). I think the latest driver dersion is 1.0.6xxx (x's are stuff I don't know specifically) something. Download it (duh). It will have a long name like NVIDIAxxxxxxxxxxxxx.run. Without X running (execute 'init 3' or 'telinit 3' or '/etc/init.d/xdm stop' as root to shutdown X without rebooting, one of those should probably work), run 'sh NVIDIAxxxxxxxxxxxxxx.run' as root. You should be able to answer 'OK' or 'YES' to all the questions asked by the installer. Once the driver is installed, follow the simple instructions in the nVidia documentation to modify your XF86Config file (it's just a matter of commenting out a few lines and adding a few, but make sure you save a backup of the original in case you do something wrong). Then restart X ('init 5' or 'telinit 5' or '/etc/init.d/xdm start' should work). If the nVidia drivers are working you should see an nVidia logo as X starts.

Thanks for the reply

I do not know if I am using a nVIDIA based videocard. The card is ATI Radeon7000, maybe someone know. But I know that the mainboard is nForce2 and I don't know if I have the correct drivers(is there some way to find out?). On their homepage it says something about merging drivers with the kernel or something and I don't know what that means. Sounds scary...

I does not seem that ATI makes drivers for Radeon 7000 for Linux.
I have tried to change the sync rates but that does not help...

T.S.

[IsaacKuo]

You are NOT using an nVidia based video card.

The videocard you're using is an Ati Radeon 7000. I also use a Radeon 7000, with no issues. I didn't install Ati's official drivers, I just use the open source "radeon" driver included with Knoppix. (I use a Knoppix hard drive install; essentially Debian).

I'm not sure what's going on with your setup yet; I'm mostly familiar with a Debian style Knoppix hard drive install. Note that you should ignore /etc/X11/XF86Config if /etc/X11/XF86Config-4 exists. In that case, XF86Config-4 is the file which is used.

[IsaacKuo]

Oh, btw--"gForce" is the name of nVidia's video cards. I guess "g" stands for "graphics", perhaps.

"nForce" is the name of nVidia's motherboard chipsets, but that's a different thing from the graphics card. The chipset is a set of communications chips which connect the computer's processor and expansion ports/slots together.

[Daedrus]

ATI website point to the following for 3D drivers for the Radeon 7000:

http://dri.sourceforge.net/cgi-bin/moin.cgi/

Linux info from ATI (also the source for the above link)

http://www.ati.com/support/faq/linux.html

[transke]

thanks for the info. here is some more info: I tried to use my neighbours CRT monitor and guess what happened? everything was ok. I was able to change the resolution and finally see all of the desktop. Not bad, but I don't feel like I have solved the problem, after all I would like to use my monitor with Linux as well. Is it a common problem in Fedora that LCD's don't work with radeon7000 cards?

Any ideas what to do next?

Thanks again

T.S.

[Daedrus]

I don't know if it is necessarily a problem with the LCD working with the video card. It might be that at any other res, the refresh rate is incorrect. I would see if you can find a way to set you res at 1024x768 at 60Hz refresh. That should work. I have had to reduce my LCD at work to 60Hz to get it to work correctly.

[transke]

I tried to play around with all of the settings and refresh rates but nothing changes. Seems that the only resolution I will get is the "640x480". Tried to install mandrake but it is the same problem. It is like I can change to any setting I would like but the program or something do not care about the changes I make.

Any ideas, anybody?

T.S.

[madcompnerd]

LCD's work perfectly with xfree.
What model LCD do you have?

We have a Viewsonic 1280x1024 at work that runs beautifully. Here are the sync rates we're using:
HorizSync 30.0 - 82.0
VertRefresh 50.0 - 75.0
Pretty close to yours, so I'm not sure if that will help or not.

[transke]

The model is Eizo L550 and I use the sync rates that is described in the manual ad at eizo.com.

it is still not working to modify the settings in the xfree86Config file. Maybe I have overlooked something? Probably it is something easy, like these problems often are, but I am now stuck.

T.S.


edit:

Linux does not find my monitor when I write ddcprobe...
