Hi Cam, That really sounds like it could be fun! Just thinking here, how to pull off that ... How about using an 'at'command. give yourself 2 minutes to change the kb, at will restart gpm then do it again 2 minutes later so you can see if new stuff works, and if it doesn't gives you time to plug in your current stuff ... :) Linux rulez! tatah On Saturday 17 February 2001 07:19, Cam Ellison wrote: > Osamu Aoki wrote: > > I agree with Carel.

What do I need to do (please be fairly > explicit, I've still got a lot to learn about this) Try this long command: # while true; do /etc/init.d/gpm stop echo -n Swap your keyboard... sleep 30 /etc/init.d/gpm start echo and try it out... sleep 300 done The sleep 30 will give you time to dis/reconnect the keyboard. The sleep 300 will give you some time to test the new keyboard (on a different virtual console that is) And the while will give several runs to try it. Stop the while with Ctrl-C.

I definitely have to reboot installing my alphas. I don't know if I had to reboot the machine with the arc-colsole, but for shure the machines with the srm-conole (fortunytely I have to install very seldom my own machines, thanx, Linus! ;-) This has something to do that the SRM-cosoles need partitions with BSD-Labels (what ever this is). I hate installing my alphas - installation is easy, but making these beasts boot is painful. But thats another story... martin

I'm quite sure that if you repartition a disk while any partition is mounted, other utilities such as mke2fs do not "see" the new partitioning scheme until a reboot.

I agree with Carel. As long as X read from /dev/gpmdata (most sane configuration but too many people disregards...), reboot is not needed for KB/mouse initialization. I just unplugged my mouse while in X4, replug -- cant move, restrted gpm to initialize, there I go again. By the way, when you have buggy multi-PC KB switcher, and KB goes crazy, restarting gpm also intialize KB nicely. I have one occasion which needs reboot.

DOS fdisk requires a > reboot to do this. Did you reboot after running fdisk when installing > Debian? fdisk can only tell the kernel to re-read the partition table when there are NO mounted filesystems on that disk. so if you repartition your root disk when booted from it you will have to reboot for the kernel to be aware of the changes. (repartitioning your root disk while running off it strikes me as a rather poor idea anyway) kernel 2.4 *might* be able to reread the partition table on busy disks, at least under some circumstances. im not sure about that. also note that 2.0 kernels had some obscure problems with rereading the partition table and it was considered good practice to reboot after altering partitions, this went away in 2.2 (and maybe later 2.0) kernels -- Ethan Benson http://www.alaska.net/~erbenson/ pgptQnqtf93yI.pgp Description: PGP signature

Ofcourse I could be overlooking something. I've read that thread you refered to, but I don't remember having seen that the really did the above, i.e. unplug the mouse, reconnect the mouse, restart gpm.
