Today I switched my Toshiba Satellite C55D-A from Windows 8.1 to Kubuntu 15.10. When it finished installing, everything seemed fine until I noticed that my desktop effects were acting very glichty.
Knowing that this was graphics issues, I checked the KDE Info Center to see if my graphics was recognized. But unfortunately, it was identifying my AMD Radeon™ HD 8210 Graphics card as "Gallium 0.4 on AMD KABINI (DRM 2.43.0, LLVM 3.6.2)".
It looks like that Kubuntu cannot find the driver for the graphics card, but I have no idea how to install the driver on Linux. Any help is very much appreciated.
