Hello ltsp-discuss! I am returning to this list after a long break. I met with a particular problem which I couldn't resolve by myself, so now I am turning to you.
I was installing a scientific/statistical application, R, onto the LTSP
server using a LTSP-client. (This is on LTSP 4.2)
The installation failed due to:
"RGL: GLX extension missing on server"
I have put output of glxinfo, glxgears -info and xdpyinfo near the end of this
letter.
I added
Load "dri"
Load "glx"
Load "GLcore"
to the modules section of xorg.conf, but it didn't help.
This client has an old non 3D graphics card (Matrox 2064W
[Millenium]), but software-rendering 3D is all I need.
I have three questions to the list:
1. I was looking for a log file from X, but didn't find any. Where is it
supposed to be (in LTSP 4.2)?
2. Can it be a lack of memory problem? The X server runs at
[EMAIL PROTECTED], but I don't know how much memory the card has (since I
don't find the log-file from X)?
3. What might be missing from my /opt/ltsp/i386/ tree that causes
software-rendering 3D to not work?
TIA, Hans
