Re: [Trisquel-users] Radeon drivers in Trisquel 4.0

[flop333]

I have been testing 4.0 (amd-64) from the live cd  on two Toshibas with  
Mobility Radeon HD 3400 Series and Mobility Radeon HD 4500. On the 3400  
everything seems to work ok, it does in fact allow you to configure dualhead  
without downloading any aditional software (up to 3.5 you had to download  
"screen-utils" or similar). On the 4500 everything seems to work as well or  
as badly as with the standard xorg radeon driver -I tested as well with  
Ubuntu 10.04-, that is, it works well but the fan works at full speed all the  
time. There is some discussion on this issue on Ubuntu Launchpad  
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/563156) and it is also  
mentioned on x.org web page under bugs for the "radeonhd" driver (not the  
"radeon" one: http://www.x.org/wiki/radeonhd#KnownBugs.26Limitations). It  
seems that installing fglrx driver solves the problem -it did in fact on this  
computer-, though perhaps some tweaking might help as well -I have not time  
currently for that-. Hope it helps.
