Screen refreshes inside rdesktop are awfully slow. Scrolling a logfile causes xorg to take 100% cpu. I'm using Ubuntu 9.04 as default as possible, no xorg.conf editing or other vga drivers. I have a ThinkPad Z60m with an ATI x600 mobility: root@tp:~# lspci |grep -i vga 01:00.0 VGA compatible controller: ATI Technologies Inc M24 1P [Radeon Mobility X600] Very easy to reproduce with default settings: - launch laptop from Ubuntu 9.04 live cd - open rdesktop or tsclient to a Windows machine - open a large logfile or a putty window - watch how the screen in building up line per line, slowing down even more near the buttom of the screen I tested other ThinkPads with other vga cards, they don't have this issue. - Z61m with ATI x1400 = ok - R61 with nVidia = ok A few more observations: - 2D and 3D in Ubuntu works fine with the new default driver (great job :-) - Visual Effects (Compiz?) work fine, on 'normal' and even 'extra', but have no effect on the reported issue. I always disable the visial effects. - scrolling in other applications works fine and fast (FF3, gedit, terminal,...) - I use rdesktop in a windowed mode (1280x960), RDPv5 - I tried rdesktop bitmap caching enable/disable, same for both - when I launch a Windows RDP inside my rdesktop, this 2nd RDP does NOT suffer the same problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/378958/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
