I am setting up an ltsp server for our small school, and I am having some issues with display corruption on certain clients. We have a number of Dell Optiplex GX60 computers that I hoped to use as thin clients. The login process works correctly, and most applications run without issues. The problem comes when trying to view certain flash videos, or when viewing complex images on the screen. Youtube videos always corrupt the display, but videos from cnn.com, for example, play perfectly. Strangely, even when the actual display is working correctly (uncorrupted), screenshots appear to be corrupted (see attached). Opening this screenshot (or any image file) in the image viewer will cause visible corruption on the terminal display. Some corruption also occurs when opening images in gimp, though to a lesser degree. Terminals using other hardware don't have any of the video corruption problems. I have tried setting the X_VIDEORAM option, adjusted color depth and resolution, but the problems persist. These systems have Intel Extreme integrated graphics, which Windows reports as Intel 82845G. From what I've read, the i810 driver should work with this chipset, but setting XSERVER = i810 in lts.conf results in a blank screen on the client. There is no bios setting for video ram, although there is an option for "Video buffer size" which can be either 1 or 8 mb. Windows reports that the graphics adapter has minimum graphics memory of 1 mb and max graphics memory of 64 mb. Perhaps the video ram is dynamically allocated? Just a guess. Any suggestions on how I can get these terminals functioning correctly?
My server is a quad-core Xeon running Fedora 11 and ltspserver 5.1.72-1
(from repos).
My current lts.conf file reads as follows:
[default]
X_COLOR_DEPTH=16
X_VIDEORAM = 1024
LOCALDEV=True
SOUND=True
NBD_SWAP=True
SYSLOG_HOST=server
LDM_GLOBAL_DMRC=/etc/ltsp/ldm-global-dmrc
SCREEN_01=ldm
X_MODE_0 = 800x600
LDM_DIRECTX=yes
LDM_DEBUG=yes
