Matthias, Not sure if you meant to send this to only me or whether I gotdropped on the LAU reply. anyway, responding with a copy back to thelist. I've used the rt-kernel with the OS ATI driver for a long time.Works fine for me. I run 1280x1024 with my ATI RV300. (Radeon X300PCIE) I'm not restricted to 800x600. - Mark lightning ~ # uname -aLinux lightning 2.6.24-rt1 #1 PREEMPT RT Tue Feb 5 07:03:44 PST 2008x86_64 AMD Athlon(tm) 64 Processor 3000+ AuthenticAMD GNU/Linux lightning ~ # lsmod | grep radeonradeon 118944 2drm 85720 3 radeon lightning ~ # xrandrScreen 0: minimum 400 x 300, current 1280 x 1024, maximum 1280 x 1024default connected 1280x1024+0+0 0mm x 0mm 1280x1024 75.0* 60.0 1024x768 75.0 70.0 60.0 800x600 75.0 72.0 60.0 56.0 640x480 75.0 73.0 60.0 1280x960 60.0 1152x864 75.0 1152x768 55.0 832x624 75.0 416x312 75.0 400x300 75.0 72.0 60.0lightning ~ # On Mon, Dec 15, 2008 at 11:51 PM, Matthias Schönborn <mbs1303@xxxxxx> wrote:> Am Montag, den 15.12.2008, 17:31 -0800 schrieb Mark Knecht:>> On Mon, Dec 15, 2008 at 3:23 PM, Matthias Schönborn <mbs1303@xxxxxx> wrote:>> > Well, the day before yesterday I built the fglrx-modules for linux-rt,>> > but now each time I try to use ardour it disconnects after a few minutes>> > with the message that jack disconnected ardour for not being fast>> > enough.
