I recently installed Ubuntu 12.04 alongside Win7 on my HP Pavillion dv6-2020eg.
Ubuntu does not recognize my ATI Mobility Radeon HD 4xxx graphics card. It just says "unknown" in the information box and also no additional drivers are found. On the other hand the graphics are all working fine, so that might not be a real problem. I also tried Ubuntu 13.04 with everything being just the same.
- CPU: AMD Turion(tm) II Dual-Core Mobile M500 × 2
- Kernel Linux 3.5.0-32-generic
- Gnome 3.4.2
A second problem I am facing - issues with suspend mode - might be related to this. I would appreciate it if you could chime in on that other Q&A as well if you have any ideas what might be causing these symptoms.
