That was actually the first thing I tried, but i get this error message pop up when I tick the “Enable desktop effects box” and then press apply:
Failed to activate desktop effects using the given configuration options. Settings will be reverted to their previous values.
Check your X configuration. You may also consider changing advanced options, especially changing the compositing type.
So I did what the message says and it all seemed peachy to me, then I tried to update it with the one-click…
It seems like all 3D acceleration is disabled, despite it being set to enabled. When i scroll through web pages in any of the browsers, it’s very slow and choppy, as is shrinking windows.
Also worth mentioning is that fgl_glxgears and fglrxinfo return the following:
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 143 (GLX)
Minor opcode of failed request: 19 (X_GLXQueryServerString)
Serial number of failed request: 14
Current serial number in output stream: 14
