x(dm) freezes at first start
hello, at boot, when xdm is started, x freezes directly after the login screen is displayed. sometimes it's possible to type in the login name, but at the latest at typing the password, the complete screen freezes. i'm still able to kill x with magic sysrq key combination: alt+sysrq+k strg+alt+backspace and changing the console screen don't work any longer. as already said, this happens _only_ at the first start of xdm, in the boot process. if i stop and afterwards start xdm, it _never_ freezes. i'm running (debian/unstable) gnu linux with kernel 2.6.8 on an amd athlon64 with a matrox g400 dual-head 32mb agp graphics card. i use the most recent xserver-xfree86 (4.3.0.dfsg.1-6) from debian/unstable with driver mga, and on kernel level the matroxfb framebuffer driver. the virtual consoles are all using framebuffer, in xfree86 config i've no options related to framebuffer set. as the magic sysrq key combination still works, the problem cannot be a hardware issue. syslog gives _no_ output while x freezes, so matroxfb upstream maintainer is confident that it's not a kernel issue either. so in my eyes only xfree86 is left to be the originator of the bug. i already posted another mail that treats the problem: http://www.mail-archive.com/[EMAIL PROTECTED]/mgs16563.html unfortunately, nobody replied to it, so i try again, with a cc to the developers list. bye jonas ps: people on the devel list, please cc me, as i'm not subscribed. ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel

It is supposed to be a lightweight protocol, so it might be a simpler task to write a vnclient for DOS. Thanks for this hint, this seems to be the easiest achievable solution, so i'll give it a try ;) Although the lowest depth vnc supports is 8bit, but this is something that can be handled somehow.

Leave religion out of this. 1) Xfbdev has always been Linux-specific. 2) Driving /dev/fb* as anything other than a dumb framebuffer isn't possible without linux/fb.h's ioctl's. rc1 is broken WRT this problem. Fix this there.
