Screen briefly becomes black

Post by dlalonde »

Hello

I have an Intel graphic card and whether I use the drivers that come by default or I activate the non-free drivers, once in a while, the screen goes black for a second and comes back. It happens during random tasks like this morning it happened when I pressed the up arrow on my keyboard while in the terminal.

How can I keep this from happening?

Thank you!

Oh and I wanted to add that this problem occurs on LinuxMint and Ubuntu Gnome but not Ubuntu Unity. Maybe that can give a clue on what's going on.

Intel doesn't really do binary video drivers ... what does it say it is in driver manager? It may be a cpu related update that isn't actually a driver but it'd end up on that list because anything that's non open source does.

To see what actual Intel video card and driver you have, along with system info, copy/paste these into terminal and copy/paste the text output here:

Code: Select all

sudo lshw -C video

Code: Select all

glxinfo | grep OpenGL

Code: Select all

inxi -Fxz

Thanks for your response. I don't know what binary video driver means though.

Your first command did this:

Code: Select all

I also have the same issue - though it seems to appear when I'm either in Firefox or watching a video in VLC
