Hi everyone, my dad have a computer that it have a integrated graphics, the CPU is a "Intel(R) Dual CPU E2160" the clock is a 1.80 GHz."

The problem is that sometimes in ubuntu mate 15.10 the screen do "Weird things", and sometimes block fully the screen, i did think that is a problem with ubuntu mate, because is a new distribution, but i remember that in other distributions, fedora etc... i too had graphics problem, for example with openshot when my dad render video, block fully the system, and some times the computer is very very slow, i have try somes DE but is not problem with a DE.

It's not a hardware problem because my dad have dual boot with windows 7 and windows 7 work fine.

Thanks.

While it's going to be an Intel GMA chip, do you happen to know WHICH GMA it is? I THINK all but the GMA3600 use the same driver, but knowing which version of the chip it is for sure would make it easier (the old GMA isn't integrated in the processor, it's integrated into the board). You can get the information from Windows or in a terminal in linux

Thanks for your reponse.

The graphics model is: "Intel(R) 82945G Express chipset family" I did see it in windows.

GMA 950

Lets try creating the 20-intel.conf file to let us specify some options, and start with trying disabling 3d acceleration entirely (which is usually the cause of lockups with this old chip.

Then restart and see if it's any more stable.

The /etc/X11/xorg.conf.d directory not exist, do i make it?

EDIT: Sorry, the directory is in /usr/share, now i going to do that you say, thanks.

Yeah, go ahead.
