I recently got an old computer to install Ubuntu 18.04.2 LTS on. I did and it worked at first, but it kept freezing and crashing.

I don't remember doing anything different, but it doesn't seem to freeze and crash anymore, but it's unusable because the screen resolution is so low.

My only option is 640x480. This is way too low. Nothing fits on the screen. In order to browse the web, I have to zoom out by 50% and it's just unbearable. I've tried every possible way to increase the screen resolution, but nothing works. The monitor supports up to 1680x1050.

The computer runs Windows 7 on a separate disk and Windows 7 works fine. For some reason, Ubuntu no longer works. I can not figure out why this is happening or how to fix it. I have tried xrandr and everything.

    As this might be GPU related, please add output from lspci -v command, you can show us only lines related to your VGA device (graphics card). – Comar May 4 at 0:34
  • Show me grep -i nomodeset /etc/default/grub. Start comments to me with @heynnema or I may miss them. – heynnema May 4 at 13:46
  • @Comar what do I look for in the output of lspci -v? It's too big to copy and paste it in here. – Rkd1767 D254 May 9 at 21:35
  • @heynnema I ran the grep command, but it didn't find anything – Rkd1767 D254 May 9 at 21:37
  • Have you installed the appropriate Nvidia video driver? In the Software & Updates app, Additional Drivers tab, tell me what you see. – heynnema May 9 at 21:41

You can reinstall the driver with the command sudo ubuntu-drivers autoinstall. then reboot, then change the resolution. if not, please see this website

How do I install additional drivers?

Maybe it work.. :)

    Thanks for all of the help. I've been wanting to get a new GPU anyway, so I finally did, and so far it works fine with the new GPU. Thanks again – Rkd1767 D254 May 12 at 0:35
