I currently am running the rc3 on a emachines d620 laptop,with an ATI X1200 express video cardhad the following issues and suggestions as follows:-
When selecting the ati proprietary driver,there is an error message that comes up briefly but i cannot read it something along the lines of there is an error with your installation of your driver,this also happened in the rc2.Upon booting the system it dumps me to a terminal screen and does not start the xserver. I then checked the xorg.conf and the driver listed was shown as radeon the xorg driver,i changed this to fglrx and the xserver started and i was able to boot and had direct 3d rendering working as well.Now on rc2 it displayed the same behavouir and selected the radeon driver but i was able to boot to the desktop,when i then changed this to fglrx it also worked but didnt have any 3d rendering enabled.
so we have some progress as far as iam concerned on one hand as i now have direct rendering enabled by the fglrx driver but also have some regression also as it does not boot the radeon driver after the issue with installation of the proprietary ati driver.
I also had an issue with my touchpad even though i selected this driver,i could not double click on any folder,i managed to resolve this from a previous post by adding the following entry into xorg.conf Option "VertEdgeScroll" "1" Option "TapButton1" "1".
i really think this should be added in a standard install from a usability point of viewautomatically as a new user would struggle to sort this minor but annoying issue out.
I also noticed some inconsitency in logging in where if you mistyped the wrong username,selecting the picture and name on the left hand side would not input your name automatically again,you had to type it in manually.
Iam using this rc3 full time at the moment and iam very impressed with it so far to say the least,it is the only distribution to set up my atheros 5007 wireless card correctly without ndiswrapper,wicd works perfectly.Mepis 8.0,Slackware 12.2 both needed ndiswrapper to suceed in this and ubuntu was a nightmare it would not work what so ever,so you should be congratulated.
