Hello there, a while back I installed manjaro on my computer alongside windows, due to the fact that it is very old (dell optiplex 755).
Before I get on to what happened, here are some specs:
GPU: Intel Q35 Express chipset family
CPU: Intel Dual-Core E5400 at 2.70GHz
RAM (don’t think it makes a difference but): 4gb
And lastly, I have 64 bits.
I kept running into the error GLXBadFBConfig when trying several apps, specially when using wine, so after I looked up online, I saw that it was likely a driver issue not being installed propperly and thus having an old opengl version. That made sense, specially considering that again, I’m running old hardware.
So, I searched something around the lines of: “manjaro opengl update” or something and came across the “Configure Graphics Cards” (can’t include links or hyperlinks, sorry). The “Overview” section of the page contains this text:
For Beginners, it is recommended to use “Hardware Detection” in [Manjaro Settings Manager] to change or install new graphics drivers.
So, since I don’t really know a lot about hardware in general, I decided to try it out.
This is where the problem began, I saw that 2 drivers weren’t installed, one of them being linux-vesa and the other one I forgot.
I installed them both manually before I realized that there’s a button that installs the open-source updates automatically, so after that I clicked that button.
Then, I hit log off so the changes would apply, and to my surprise, it had installed software that was way too new for my computer, leaving the device practically unusable.
I am unable to provide a photo of the effect it left behind, but half the screen is obstructed. I might be able to provide a recreation of the effect if needed but I don’t think it’d be needed, specially when I’m not looking for a workaround of some sorts so I don’t have this issue: I’m looking to downgrade drivers
So - I’m pretty sure there’s a way to downgrade, but I don’t know how. How can I downgrade my video drivers? And, is there a way to proove if this was a mistake on my end or the system’s end?
I apologize if I’ve missed some things or spelt things terribly as I’m not native and I don’t really understand this topic either.
Also, if I have to reinstall manjaro (seems like easiest solution but the least practical one) I’m okay with it as I’ve been using it for less than a week, and haven’t started anything super important yet.
