use mouse gestures in fvwm2/suse

easystroke is a wonderful program that lets you record mouse gestures and executes
commands based on them.
In conjunction with a special definition in .fvwm2rc you can specify any action
to be executed. For example to switch to a special window on the desktop:
in .fvwm2rc:
Key Pause A N FocusWindowNumber 8
-> switches to the window remembered on position 8
PipeRead 'for i in `seq 0 9`; do echo Key $i A MC AssignNumberToCurrentWindow $i; done'
->remembers the window and stores it on position 8

in easystroke define key "Pause" to a gesture of your choice.

If executing that gesture the window 8 is switched to.

wacom bamboo stops working after unplugging

to solve this (to get it working as a graphic tablet again without restarting X) just switch from X11 to Console (press Ctrl + Alt + F1 together then release them) and then switch back to X11 (press Ctrl + Alt + F7 together then release them).
Then the graphic tablet works as before unplugging!

grub

Error 18: Selected cylinder exceeds maximum supported by BIOS
-> the bios is too old and the kernel is byond the 8 Gbyte limit

Install the grub from rescue disc:
mount /dev/sda? /mnt/sysimage
mount --bind /dev /mnt/sysimage/dev
chroot /mnt/sysimage
grub-install /dev/sda


IF the partitions are as follows:
/dev/sda1 windows
/dev/sda2 extended
/dev/sda5 swap
/dev/sda6 /
/dev/sda7 /home

then you need to set /dev/sda2 as the boot partition with fdisk /dev/sda a 2
in the menu.lst of grub needs to be written: root (hd0,5)
