OpenGL/graphics problem

[robotichead]

I have a Dell Inspiron 1525.
When i was running 8.10, i did not have this problem. I've only been having this problem with 9.04. When i try and use blender, or any other application that uses OpenGL. It seems to do something funny, and not display correctly.


As you can see, the modeling area is not displaying correctly, and also none of the butters are showing...

Why is it doing this. And is there a fix without having to reinstall ubuntu?

Thank-you for your time

Is Compiz turned on? Compiz has issues with some full screen applications, such as Blender.
You can disable it from System->Preferences->Appearance on the Visual Effects tab.

A better way is to install fusion-icon. Fusion-Icon is available in Ubuntu and other distributions' repositories, so it is very easy to install it.

sudo apt-get install fusion-icon

Or you can use Synaptic or Adept package managers.

After it is installed you can find it in Applications->System Tools. When you run it, an icon will appear on the upper system bar on the right side.Select window manager->metacity and the effects are disabled. Select window manager->compiz and it is enabled again.

To have it starting at boot, go to System->Preferences->Sessions click add and in the command field put

fusion-icon --no-start

i currently have the visual effects turned off, and after doing all that. its still doing what it was doing before.

What graphics card do you have?

I've found with several older or cheaper graphics chips the OpenGL only runs one app reliably and only at 1024x768 resolution or less. May have problems with resizing GL windows as well.

If you start the app with a render window of less that 1024x768 and are still having problems, I'd check into using an older version of the graphics driver (what ever one worked in 8.10 ).

lspci -nn | grep -i vga

cat /var/log/Xorg.0.log | grep drv

As for the graphics card, i think its just intergrated into the mother board. Most likely Intel.

I typed out those commands and this is what i got

luke@luk:~$ lspci -nm | grep -i vga
luke@luk:~$ sudo lspci -nm | grep -i vga
[sudo] password for luke: 
luke@luk:~$ cat /var/log/Xorg.0.log | grep drv
(II) Loading /usr/lib/xorg/modules/drivers//intel_drv.so

The intel driver is known buggy, the above screencap is a good example.

I hate to say it, but I think your best option is to find out what interface you have for installing a graphics card, then get one with an nVidia chipset. nVidia has the best vendor supported drivers in the Linux market. Install an nVidia card and disable your internal Intel graphics, I think you will not be disappointed.

Problem is, i have a laptop. So installing a new graphics card is out of the option, and i know that i did not have this problem with ubuntu 8.10.

The Intel driver in Ubuntu 9.04 has serious issues, I faced them in my laptop and for this reason I still use Ubuntu 8.10.(At home I use 9.04 with Ati card)
The next Ubuntu version 9.10 will be released at the end of October and has better Intel drivers. I tried the Alpha version in my laptop and 3d graphics were fast and problem-free. You 'll have to be patient for 1,5 month I guess...
