AMD 3400+, 2GB RAM, GeForce FX5200 (AGP likely, but not 100% sure)
Kubuntu 10.04 and 12.04 32b, no fancy repos. Mozilla Firefox.
Used to run flash plugins fairly well, then all of a sudden stopped working in 12.04. Only shows a black rectangle in youtube.
My guess: either X or flash got updated and broked.
this was on 10.04, told the user to wait until 12.04 is out. So today upgraded.
Found that even while I installed nvidia-173 it won't load as nvidia is still working on getting the 173to work with the new kernel API ( I wonder tho: why is 173 then released? In an LTS?).
So right now it's nouveau.
12.04: still no flash. Tried flashplugin-installer, tried adobe-flashplugin, tried purging this and uninstalling that and copying the .so manually to moz' plugin dir - nuthin.
Cannot tell the culprit, have no idea where to look, what to try.
