Hello, I have just made my first experimental install of LTSP. The server is Mandrake 9.0 and I used rpms from sourceforge as they seemed to install OK. The etherboot nic is a tulip lne100 from diskless workstations with onboard bootrom. Between the ws001 (which is an old p166 desktop w/32 MB of RAM) is a 100base-t switch. The server also has a 100base-t nic.
With a little scraped knuckles everything is basically working. Praise be to LTSP.
However, there is this weird flickering of the root window. Like part of the GDM window appears to be tearing off from the login box and appears slightly displaced to the right. It flickers like this appearing and disappearing in less than half a second.
This is an 1996 vintage desktop from IBM with S3trio builtin video chipset and 1 MB ram. I know desktops like this will do 1024x768 at 16 bits, but this setup is producing only a 800x600 desktop and this flickering problem. I altered lts.conf for ws001 so that it used an NFS swap file to increase the locally available RAM but it didn't help.
Could the flickering be network related?
Or is it simply not good enough a video chipset for use with LTSP ? I installed the Xfree86-3.3.6 server for S3 instead of going with X4. I tried X4 at first --it didn't seem terribly happy. I don't think these S3trio chipsets were well supported by X4 until X4.3. I 've also never known this flickering or desktop size limitation to happen with a system built on this desktop with a normal (local) install. I don't recall ever seeing such bad artifacts with remote X display either.
Is this unusual?
Do I just need to buy some halfway decent video cards to make this go away?


thanks.
