Bug Description
Binary package hint: xserver-xorg
Release : Kubuntu 10.04 RC AMD64
Package : xserver-xorg
Problem Description : When starting live CD session instead of logging in to a Kwin interface it starts on console mode (meaning that the hole screen is the console). Trying to explicit start the kwin reports that no X server is not running. Trying to start the X server explicit leads to a blank (black) screen. When power down (button press) i can see the init cursor
of the X server (X) instantly and then i am directed to the console again for something like a second and then to the blue GUI screen with the kubuntu logo prompting to remove CD. In both cases of start-up and shut-down the GUI screens with the logo of kubuntu are shown.
Hardware Information :
VGA compatible controller : ATI Technologies Inc RV730 PRO [Radeon HD 4650]
Host bridge : ATI Technologies Inc RD790 Northbridge only dual slot PCI-e_GFX and HT3 K8 part
Audio device : ATI Technologies Inc SBx00 Azalia (Intel HDA)
Audio device : ATI Technologies Inc R700 Audio Device [Radeon HD 4000 Series]
CPU : AMD Phenom(tm) II X4 965 Processor
Motherboard : MSI 790FX-GD70 (790FX Northbidge)
Notice that the 9.10 version of kubuntu works fine on that hardware. Also notice that in the working 9.10 version i am using a custom kernel 2.6.32 (official) with custom built fglrx 8.712 (ATI 10.3 official driver). In the 9.10 release i had similar problems with the 10.2 ATI driver. So i assume that is either the X Server or some faulty driver package (if any is used). The X.Org X Server 1.6.4 of previous version seems to work fine with both 2.6.32 kernel and the latest ATI fglrx drivers (with the exception of 10.2)
I hope this info is useful for a better release.

This is possibly https:/ /bugs.freedeskt op.org/ show_bug. cgi?id= 29834 which is fixed upstream in kernel 2.6.35.8. From the changelog:

drm/radeon/kms: fix potential segfault in r600_ioctl_ wait_idle
commit e488459a0e131ac c9e14df093cfee7 40bc431953 upstream.
radeon_ gem_wait_ idle_ioctl can apparently get called prior to
the vram page being set up or even if accel if false, so make
sure it's valid before using it.
Should fix: bugs.debian. org/cgi- bin/bugreport. cgi?bug= 597636 /bugs.freedeskt op.org/ show_bug. cgi?id= 29834
