Problems with OpenGL in Ubuntu Feisty

[drewfus]

I keep getting an Indirect Rendering error. When I try to launch the updater the video flickers like crazy. I tried this from another post "..Open up the file [PS Directory]/data/config/r3dopengl.cfg in a text editor, and find this line:
Video.OpenGL.FontCache.UseMultiTexturing = yes" and it at least displays in english now instead of flickering Japanese. I get the errors:

:~/PlaneShift$ ./psclient

  Indirect rendering may indicate a flawed OpenGL setup if you run on a local

Any suggestions? I may have not searched hard enough in the threads but I'm stumped.

Thank you.

First lets see if you actually have direct rendering enabled on your computer. 

Open a terminal   -  Applications ---> Accessories ---> Terminal

Enter the following command:

Code: [Select]

glxinfo | grep direct
And paste the output of that command as a reply in this thread.  We'll go from there once we have that information.

I seem to be having this problem as well. The output of that command is:
blitzgren@hServ-v2:~$ glxinfo | grep direct
direct rendering: No
OpenGL renderer string: Mesa GLX Indirect

This means hardware 3d drivers are not installed. What is your video card?

[drewfus]

mine isn't enabled either, i  use nvidia

[Induane]

To install the correct driver, click on the System Menu and select Administration.  Inside that should be a "Restricted Drivers Manager" somewhere in the list.  Click on that.  Mine looks like this:



Make sure to checkbox and enable the driver for your card.  If you have an ati card there will be an option for that instead of your nvidia option.  Once its enabled and installed (will take a bit to apply) you can use CTRL + ALT + BACKSPACE to restart X without restarting the computer.  This way you can change to the new video driver quickly without a reboot.

Also, if you have a GeForce4 videocard be warned as it may not work.  Nvidia doesn't support that card well and you may end up with a black screen.  Its worth googling around to see what other people have come up with as solutions for this problem, but afaik it only affects the geforce4 series.

Having looked at some of this lately I've come to the conclusion this is only going to get worse. The last version of the nvidia proprietary driver that works without problem for my chipset is the 8776 version. Nvidia seems to have settled on a three track driver system: the current driver and two strains of legacy drivers. Unfortunately for me the 8776 version is two releases back from the middle driver (96xx) which gives me that black screen. You can tell it is not going to work because the nvidia splash screen appearing when x is loading had a black background instead of the normal white. It works fine for some OGL applications and not at all for others as can be seen looking at the OGL screensavers. It may be possible to fix by adding an option to the xorg.conf file:

Option "AllowGLXWithComposite" "true"<< to the device-section in /etc/X11/xorg.conf.

but I am not certain yet. My Fedora partition is in that non-functional state now, my Ubuntu is not currently bootable, I am going to test this anyway and report if it fixes the problem. If it works in one it should work in another.

Edit: adding the option did nothing apparent, I'll have to fiddle with it some more later.
