Ubuntu uses only the top left quarter of the screen

Question

I'm using Ubuntu 16 live on two PCs and both show an image only on the upper left quarter of the screen. How can I resize it since I cannot go to settings the normal way?

Could you please [edit] your question to include the output of the terminal command lspci -nnk | grep -A2 VGA and xrandr? Thanks. — David Foerster, Feb 13 '17 at 04:36
If you cannot get to the terminal via the GUI, you can press Ctrl + Alt + F1 to change to the vt, and press Ctrl + Alt + F7 to get back. Sometimes doing this also (temporarily) fixes problems like this. — Jonas Czech, Feb 13 '17 at 06:35
I've got the same issue on Pop!_OS 22.04. Here's a gist with output for the commands mentioned by @DavidFoerster. — Daniel Himmelstein, May 04 '22 at 01:39

I encountered the same issue on Ubuntu 16.04 when launching some Steam games.

The only solution I have found is to restart the display manager, at the cost of logging out and losing the session.

I do not have enough reputation to comment on the original question... for me the output of lspci -nnk | grep -A2 VGA is: 00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09) DeviceName: Intel(R) Graphics 4000 Subsystem: Hewlett-Packard Company 3rd Gen Core processor Graphics Controller [103c:18f9] – ryhui Mar 11 '17 at 21:57
xrandr: Can't open display – ryhui Mar 11 '17 at 21:58
