Mandriva refresh rate problems

[Pasch]

Hi there,

I recently changed my graphics card from a Sapphire Atlantis Radeon 9600, 256MB to a Sapphire Radeon X1600 Pro, 512MB (both AGP 8x), and I've been having some trouble getting the refresh rate up in Mandriva since. It's been about a month and I just can't get the refresh rate up to a decent level.

The refresh rate in Windows is fine and I've done some tests on the card so I know the hardware is fine. It shows up as a Radeon X1600 in the Linux device list, so it appears it is recognized okay.

The first thing I tried to get the refresh rate up was simply go to the desktop properties and change it from there. That didn't work, the refresh rate was locked at 43hz and it wouldn't allow any other rates. I tried changing my monitor type, but that didn't work either. First I tried setting it to it's exact type (Compaq S710), which didn't work. I've also tried some of the generic settings, which didn't work either. Finally I tried setting a custom monitor (with a custom vertical and horizontal refresh rate), and now according to the desktop properties the refresh rate is up to 71hz, which still hurts my eyes. In the custom configuration I set the horizontal and vertical refresh rates to 68.6 k and 85hz, which is the same as in my Windows, so it should be running at 85hz.

I've tried editing the xorg.conf file, but, even though the refresh rate is still low, it looks in order to me. Here's some parts from my xorg.conf file that I think are relevant in this situation:


Section "Monitor"
Identifier "monitor1"
HorizSync 68.6
VertRefresh 85

Then later on:

Section "Screen"
Identifier "screen1"
Device "device1"
Monitor "monitor1"
DefaultColorDepth 16


It looks to me as though the settings for "monitor1" are correct, they're the same settings I use in Windows, and the monitor is indeed set to "monitor1", so I'm really unsure what to try next.

Any help would be much appreciated. I'm running Mandriva Free 2007 and I want to set my screen to 85hz (resolution is 1024x768). I'm using KDE.

Thank you for reading.

Try to put in 30-70 for hsync and 50-160 for vsync into your xorg.conf file, this is the range for your monitor.

BTW, what's your opinion on Mandriva 2007..? im about to download the free version too.

I'm quite happy about it, it's never given me any serious problems until this. I do recommend it.

I've tried it but still it won't go up. It's as if something else overrides whatever I put in.

Do you use the ATI driver or the XORG driver for your video card? Could you attach your xorg.conf file? I will try to have a look at it tonight.

I'm using the fbdev drivers. Attached is a copy of my xorg.conf file and a screenshot of my hardware settings for the graphics card. I had to put the xorg.conf file in a RAR file as it would not let me upload it otherwise. Thank you in advance for the help!

That's a very minimalistic xorg.conf. I suggest you try to install the ATI drivers, they are not great but should at least detect your video card correctly and give you more options. I can't help with their installation on Mandriva because I never used it. Just for fun, here is my xorg.conf.

I'm trying to install the official ATI drivers, found on their website. They installed fine, and I ran ATIconfig which went fine as well. However, when I reboot, the X-server won't start and the following errors are in the log:

Can't open or find libstdc++.so.5
(EE) Failed to load /usr/lib/xorg/modules/drivers/fglrx_drv.so
(EE) Failed to load module "fglrx" (loader failed, 7)
(EE) No devices detected.

Fatal server error:
no screens found

I've tried uninstalling them and installing them again, but can't get them to work. I followed the instructions on the ATI website, though they did differ a little from what I actually had to do. Still I'm quite sure I did it right. I can't seem to find any of the packages that it claims to be missing in my packages list.
