Video Depth Problems.


I have an nVidia 6600 graphics card and have always seemed to have problems with getting X configured correnctly, although i did manage it in 6.06 i have just installed a fresh install of 6.10 off the live CD.

In order to get the live CD to boot with a graphics setup that could be displayed i had to change the mode from default to 1024x768 @ 32bit depth.

After install again i cannot get onto the desktop, i have booted to the command line and run the xconf config program however this still doesn't work and have tried to manually edit the xorg.conf file so the depth is 32 however i get an error when i try to run startx saying that this isn't suppored by my devices.

Can anyone help?

Thanks.

Try changing the depth to 24 instead of 32.

it is on 24 by default, this doesn't work either. Having booted the live CD again and looked at the xorg.conf that is booted and seems to work ok off the live CD the only difference i can see is that it identifys the card as opposed to using a generic identifier. could this be part of the problem?

If X works fine using the live cd, run the live cd, copy the /etc/X11/xorg.conf and then paste it in the Ubuntu installation on your hard drive.

Yeah, such things are very annoying. Do other distributions work well with your card?

Available resolution and depth are specified in xorg.conf but what you can get is a function of the driver. If a driver doesn't support what you've requested it will use its closest choice. Perhaps the driver you've installed doesn't support your video card. Nvidia for example has an open source choice "nv" that supports all Nvidia chip set with a limited feature set. There are two proprietary drivers. One for older "legacy" cards and the other for all newer cards. Xorg from the live CD probably called out the "vesa" driver which will support cards from all manufacturers with a limited feature set.

Ok just a little update i was trying the NV driver, and the card is a 6600 GT. In other distributions i have mixed results, fedora i get the same problem however Linspire works fine straight off.

A friend of mine has suggested that it might be a monitour issue and a improper refresh rate is causing however i have no idea how to change this at all, and niether had he so i am still stuck really.

I have tried running X and changing the resoultion with the Ctrl+Alt and + & - keys this makes no difference at all to what appears on the screen.

Nothing in X seems to have crashed since the 'welcome' sound plays ok.
