I'm trying ton use my Mobility Radeon HD 4650 with Kubuntu 14.04. I've seen that the propriatory driver doesn't work with Kubuntu 14.04 and the new kernel and that I must use the free radeon driver. This is my laptop : http://doc.ubuntu-fr.org/toshiba_satellite_p300-27z/
But I've 2 problems :
- After installing (with "nomodeset" to get installing working ; without "nomodeset" it freezed), my screen only works with à 1152x864 resolution and no possibility to choose 1440x900 which works fine with 12.04 and fglrx drivers.
- my laptop is hot ; this was not so with propriatory driver
I tried more things but nothing works, so I need your help.
Thank's
