Dear John and Jean-Pierre,<br><br>Finally I could solve this problem.<br><br>I realized that the graphics driver my installation automatically configured was not the ideal one, though all the graphics otherwise were perfect. I included the original nvidia software repository (<a href="ftp://download.nvidia.com/opensuse/11.2/">ftp://download.nvidia.com/opensuse/11.2/</a>) in yast and looked for suitable nvidia driver. I found that my system could successfully install and configure the driver "nvidia-gfx-kmp-default". I then added the line Option BackingStore "True" in all instances of Section "Device",and restarted my X11.<br>
<br>To my great relief, my GrADS display is now perfect, and I no longer need to redisplay the graphics whenever the window is overlapped by others. Also, my X11 is behaving perfectly even with BackingStore turned on.<br>
<br>"xdpyinfo -display" still shows "save-unders NO", so that was not a critical issue.<br><br>Thank you both for your feedback.<br><br>Cheers,<br>Kumar.<br><p style="margin: 0px; text-indent: 0px;"><br>

Hi <br><br> Seems like a backingstore option problem. Be careful when enabling this using nvidia drivers - on opensuse 11.1 enabling backing store led to X no longer working and serious boot up problems. I now just live with the loss of the display when changing desktops etc.<br>

graphics window of GrADS is overlapped by other windows, I find that<br>the overlapped portion is wiped clean and I have to explicitly<br>redisplay the graphics. I used to work around this problem earlier<br>with "Option BackingStore on" in the XF86 configuration. However, in<br>
my present installation of OpenSUSE 11.2, the BackingStore option in<br>the configuration file "xorg.conf" no longer seems to have
any effect.<br><br>I would greatly appreciate any clue to solve this problem.<br><br>Thanks,<br>Kumar.<br>--<br>========================================<br>Dr. Rupa Kumar Kolli<br>Chief, World Climate Applications & Services Division<br>
