I installed Lubuntu on an old laptop. Everything was fine until I installed updates the other day. After the updates, the graphics were messed up. The menu and the bar at the bottom of the screen are ok. Also, if I open a terminal, that is clear too. I'm about to just reinstall everything but wanted to ask here first.

I am really not good with computers, but here is the hardware info:

Toshiba Satellite C655
Ubuntu 20.04.2 LTS
5.4.0-77-generic
Pentium(R) Dual_core CPU T4500 @ 2.30GHz
MemTotal: 3897504 kB

Graphics: Device-1: Intel Mobile 4 Series Integrated Graphics driver: i915 v: kernel
          Display: x11 server: X.Org 1.20.9 driver: modesetting unloaded: fbdev,vesa resolution: 1366x768~60Hz
          OpenGL: renderer: Mesa Mobile Intel GM45 Express (CTG)
          v: 2.1 Mesa 21.2.0-devel (git-7de5293 2021-07-18 focal-oibaf-ppa)

If there is some other hardware info I need, I know how to type in the terminal.

cat /sys/devices/cpu/caps/pmu_name: core2

Graphics problem caused by using 3rd party drivers (oibaf). The following fixed the problem:

$ sudo apt install ppa-purge
$ sudo ppa-purge ppa:oibaf/graphics-drivers
Reboot
