Hi. Total newbie here. I have a problem with my screen. Itøs blinking at me.
It seems I have to update my graphic card driver, but how do I do that?
How do I find one?

As it's hard to give you an exact answer without knowing more details about your system.

Hello and welcome to the forum :)

First, please read the information here. The more information we have, the better we can help you. ;)

What is the brand and model (and model number) of your computer? Which distribution and version of Linux did you install? How did this problem come about? Right after you installed Linux or after a program? Also, please open a terminal and post the results of these commands...

Code:

lspci -nnk | grep VGA -A 12

Code:

glxinfo | grep -i vendor

This will give us more information concerning your graphics chip. :)

Regards...

So sorry for not giving you enough info. I will try to do better in the future :-)

The second answered this>

The program 'glxinfo' is currently not installed. You can install it by typing:
sudo apt install mesa-utils
(I will install this now)

My version is Ubuntu 16.04 LTS. The problem started after having completed the installation and installing Google Chrome.

:-) Thank you for taking the time to help me!!

Does it blink often? Infrequently? Very fast? All over the whole screen, or just parts?

What operating system did you use before 16.04? Was it working OK?

What brand and model is your PC?

Please find the file /var/log/Xorg.0.log and attach it here.

Run this command in a terminal:

Code:

sudo dpkg -l | grep intel

and report the results. If among the results you see xserver-xorg-video-intel, you can try switching to a different driver by doing:

Code:

sudo apt-get purge xserver-xorg-video-intel

and restarting the X server or rebooting. If this does not resolve the problem, attach the newer Xorg.0.log file when you report your results.

I've tried to upgrade driver, so now we wait.

Thank you so much, mrmazda! I'm going to reboot and see what happens over the next couple of hours. There's no real pattern in the blinking and it didn't blink, when I had Windows 8 (before installing Linux). My computer is an Acer Aspire Intel® Core™ i7-3517U CPU @ 1.90GHz × 4, 64/bit, with a Samsung 500 GB ssd harddrive. Is that enough info?
