re-enable 3d graphics

[terpic]

How do I re-enable 3D graphics support?

I had the nvidia drivers installed and foolishly changed the colour resolution to 24 bit from 16 bit. when I rebooted 3D support was disabled, I changed the colour back to 16 bit but 3D support is still disabled. I am running SuSe9 and have looked in Yast2 and sax2 but can't see what to do.

Thanks for any help.

Can you post your /etc/X11/XF86Config file? Maybe we can spot the problem there.

this is the contents of my /etc/x11/config file

if you are referring to "3d support" in the SuSE Yast interface then ignore it... it is a wrong/stupid.

open a terminal and run glxgears. if it runs and you get a decent frame rate then 3D is enabled.

also: you are using the generic (un-3d-accelerated) nv driver.

change:

Driver "nv"

to:

Driver "nvidia"

Which is in the Nvidia/SuSE readme.

How do I edit the code,I tried by opening the file in kwrite, but couldn't save the changes.
I have never managed to get into a file in konsole to be able to edit it.

glxgears wouldn't run so I assume the 3D graphics are not working.

[terpic]

I originally had the nvidia drivers installed and working with Yast2, online update, a nvidia splash screen came up at boot, before kde and I could use games that needed 3D graphics. After I altered the bit rate to 24 bit then back to 16 bit there is no splash screen and when I start a game a box tells me that 3D is not configured and the game will not work.

would it be possible to uninstall the drivers and reinstall with yast on line update? If so where can I find them and how do I uninstall them.Although I would prefer to reconfigure the 3D card.

You need to be root to edit with save for any files in /etc.

Manually download the Nvidia drivers, execute the install script and it should uninstall the current installed version first.

sh NVIDIA-Linux-x86-1.0-5336-pkg1.run

sax2 -m 0=nvidia (0 is a digit, not a letter!)

Backup /etc/X11/XF86Config or XF86Config-4 before reinstalling the Nvidia drivers as the sax2 command will likely overwrite your existing X config.

I'm afraid this is turning into and unequal struggle so I think it would probably be easier to scratch this installation and reinstall, then update in Yast 2.

just a couple of questions, if I copy my home directory to another partition then reinstall linux will I still be able to transfer things like e-mails across to my new home directory and if so how?

[terpic]

It looks like everything is ok, I opened Yast2 and checked the enable 3D graphics box,and this time as well as finalise I clicked apply. now the nvidia drivers are working and I checked my etc/x11/xf86config file and instead of the nv driver I am using the nvidia driver, also glxgears is showing a rate of 17240 frames in 5 seconds which I assume is ok. Suse must have fixed any problems they had.

Thanks for your time and advice though.
