Graphics Messed up after updating Lubuntu

mx flag

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

Please edit the question and add hardware specifications, other than "old laptop" and also the Lubuntu release.

You didn't provide release details; which give us details as to your software stack (more clues). I would **not** re-install; but at `grub` (ie. the boot loader that should appear on boot before you see the Lubuntu `plymouth` screen/graphic) At this I'd use the *Advanced Options* to boot using an older kernel where the issue shouldn't occur I believe... That will provide clues but I'd want your *unstated* release details before I gave more (I'd also consider filing a bug as it sounds like a regression (https://phab.lubuntu.me/w/bugs/ with bug likely filed on `linux` but I'm guessing)

fyi: the `grub` menu is briefly discussed in this page on the menu (https://manual.lubuntu.me/stable/A/tips_and_tricks.html?highlight=grub), also note as I don't know your release I've provided the latest *stable* link to the manual (change *stable* in the URL to say *lts* if you're using 20.04) also fyi: when I said guessing it's *linux*; I'd normally `sudo lshw -V video` to confirm what kernel module (driver) your using & use that to adjust; but `ubuntu-bug linux` will likely suffice....

How did you install the mesa stuff? I think toshiba c655 uses Mesa DRI Intel HD Graphics 3000 and not GM45 Express but I could be wrong.

I don't know if I did install the mesa stuff. At one point, I was attempting to install Java Minecraft which did not go so well. Either it supports the mesa out-of-the-box or perhaps I did something trying to get Minecraft to work. Honestly, I don't even know what mesa is.

Also, is `i965-va-driver-shaders` installed? Check `sudo apt update` and `sudo apt install i965-va-driver-shaders` and then reboot. Additionally, I'll try to see if I can find some info on the GM45 thing. I had a c655 but swapped the CPU out for an i3 so that might be why it's different.

Okay, I found some info. Please run the following command and include the output in your question. Thanks. `cat /sys/devices/cpu/caps/pmu_name` This should report something like "sandybridge" or something else.

Okay, that is probably why it's GM45 so that's okay. According to [this answer](https://askubuntu.com/a/578446/167115) they a fixed similar graphics issue by installing `sudo apt install xserver-xorg-video-intel` and reboot to apply the changes.

Please let me know if that fixes your issue. If so, I will mark this as a duplicate. Thanks

Unfortunately, the sudo apt insall xserver-xorg-video-intel did not fix the problem.

The only other thing I can think of is to try google chrome and [disable hardware acceleration](https://askubuntu.com/a/679282/167115) to see if that fixes the issue.

You are using 3rd party drivers (oibaf) which I know little about (except they prevent *release-upgrade* in the future) so I'd look there. Your issue is not a Ubuntu bug, but related I suspect to the 3rd party drivers.

I want to thank everyone for their help. I fixed the problem. The following commands fixed it: sudo apt install ppa-purge and then: sudo ppa-purge ppa:oibaf/graphics-drivers

Please write your 'answer' in the answer section below. You can then (*in a few hours*) accept the answer as the answer and grain some *reputation* (*assuming you don't like another offered answer better*)

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

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
