INightmare's ideas

Yesterday was the day when I upgraded to KUbuntu 10.04. Installation went without any problems. And the quality stroke me.

The good part

ALSA has finally detected my audio card correctly and I didn't need to specify the model manually. So jack sensing finally works correctly.
All of my hardware was found and works correctly. Even the WiFi.
Also KUbuntu seems to start a little faster, on my Asus laptop with 2Ghz Turion and 2GB RAM it takes me to complete working desktop in less than 50 seconds counting from power on. KUbuntu looks elegant as always, though nothing really changed in the UI.
After the first boot it showed a popup message which suggested installing few proprietary packages such as Flash and some codecs.
Also Ubuntu seems to use the opensource radeon driver for ATI cards. But that will be also mentioned in...

The bad part

All went smooth accept occasional crashes of the whole system. Testing some things led me to make a conclusion on whose fault it is - X server. Radeon driver has some issues with 2D acceleration, but that is easy to solve. You need to generate xorg.conf (as new X server doesn't need that by default).

Stop kdm:

sudo kdm stop

Then build Xorg configuration

sudo Xorg -configure

This will create xorg.conf.new in your home directory. Copy that to /etc/X11/xorg.conf

sudo cp /home/username/xorg.conf.new /etc/X11/xorg.conf

Open up configuration and find the line: Driver "radeon"
Add this line below:

Option     "RenderAccel"    "False"

Reboot and crashes should be gone.

The end

Enjoy the distribution, though nothing really new, but the release is more stable and hardware support is better.
