** Description changed: I run Ubuntu on a first-generation Macbook Pro (dual-core x86; Mobility Radeon X1600), using the 'radeon' video driver, wdm as my X display manager and Blackbox as my window manager. Under Intrepid everything worked fine, however upgrading to Jaunty resulted in the following symptoms: - after logging in the X-server process begins to persistently use about 60% of CPU power, even with the system being completely idle; - opening X applications takes more and more time: for example, launching the xterm originally takes only a split second as before but trying to do that again a few minutes later implies having to wait for OVER ONE MINUTE from selecting the option from the menu till the moment the window actually appears. The slowdown affects only X applications, whatever I may run e.g. inside an already-active xterm runs just fine; - X seems to crash once in a while - all of a sudden I find myself looking at the wdm prompt again. The word 'seem' has been used because oddly enough I cannot find any trace of such crashes in X logs. The problem is quite clearly related to either the X server or its drivers, as forcibly downgrading xserver-xorg to the Intrepid version (uninstall, switch apt sources back to intrepid, reinstall) makes these problems go away despite the fact libX11 from Jaunty is not entirely compatible with the X server from Intrepid. Please let me know if you need any more information. -- MS + + [lspci] + 00:00.0 Host bridge [0600]: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub [8086:27a0] (rev 03) + Subsystem: Intel Corporation Device [8086:7270] + 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc M56P [Radeon Mobility X1600] [1002:71c5] + Subsystem: Apple Computer Inc.
