Hi,

I have just installed a very minimal Debian system on an old PC, with the intention of using it as a development platform for an embedded system.

Part of the embedded system involved a framebuffer-based GUI that I wrote many years ago. When I run this (which works fine on the office's SuSE workstations and RedHat servers), it terminates without doing anything. Doing 'cat /dev/fb0' returns '/dev/fb0: No such device', despite the fact that fb0 does actually show up with 'ls /dev'.

Some of this may be irrelevant, sorry folks, but here's a dump of lsmod if it helps:

fbcon-cfb16 3848 0 (unused)
af_packet 6152 1
unix 11352 5 (autoclean)


Also, on a side note, how do I find out the vesion of the *running* kernel (which may not be the same as the one for which I have the source).

Any feedback would be greatly appreciated,

Regards,

Alex.
