[GRASS5] Linux KDE: GRASS monitor does not refresh

GRASS GRASS developer
1

Hi all,

recently I switched to KDE 1.1.2 (SuSe 7) and have the problem,
than the GRASS monitor does not refresh if hidden by another window
and put back into foreground. It remains black.

Does anyone have an idea how to fix this?

Thanks!

Markus

It seems exposure events not being generated.
One trivial way could be to enable backing-store in the X server
(more memory needed by X)

In /etc/X11/xdm/Xserver

change a line like this

:0 local /usr/X11R6/bin/X

to

:0 local /usr/X11R6/bin/X -wm

Hope this help. Ciao

The "backing-store" thing was the right idea. I had to
add
  Option "backingstore" "on"

to the
  Section "Device"

of /etc/X11/XF86Config as I am using Xfree4. Now it works o.k.

Thanks a lot

Roberto,

mhhh, it's still not perfect. At least the background is not copied into
the monitor any more but the contents (site list crosses) still
dissappear.

I will try your -wm now...
