subject: ltsp, "XF86_FBDev crashed when non-root user login " ------------------------------------
detail: I test ltsp on one server and workstation A , workstation B
1. ltsp server: RedHat linux 70, xwindow 4.0.2,
2. workstation A: clone PC with S3 video card,
case A-1: with complete installed to Hard Drive from RedHat 7.0 CD , local boot ok, local Xwindow ok. run: X -query MyLtspServerName graphical login wndows appear,root user or non-root user login ok , all work fine. case A-2:
on ltsp server ,installed ltsp_x336_s3-3.0.0-0.i386.rpm rebuild kernel and for S3, run buildk to add ltsp header for this new kernal remote boot ok, after remote
boot,
graphical login window appear,root user or non-root user login ok , all work fine. 3. workstation B: Geode all in one board, with National Semiconductor's SC2200 Geode case B-1: with complete installed to Hard Drive from RedHat 7.0 CD , as per the NS suggestions
by:
do the kernel change to 2.4.0 and Xwindow version change to X4.0.1 download file :

----the error message on client
PC :

this crash to [EMAIL PROTECTED]
.... NO core dump file on server side or client side even i modify start_ws as: /usr/X11R6/bin/XF86_FBDev -query 90.0.0.70 -core still NO core dump file on server side or client side my start_ws for case B-2: /usr/X11R6/bin/XF86_FBDev -query 90.0.0.70 this file root user login ok ,but non-root user login crashed. i tried to modify start_ws to
disable access control
restrictions:
/usr/X11R6/bin/XF86_FBDev -query 90.0.0.70 -ac then both root user and non-root user login will crashed at the same point ---- server aborting.... eip: 0817b37b .... Call Trace: 0817d266 .... code: 8b 84 10 e4 00 00 00 89 45 e4.... Please forward information about
this crash to [EMAIL PROTECTED]
.... ============================================================================= because ltsp login ok for both root and non-root user on: case A-1 standalong linux use S3 driver , case A-2 use ltsp_x336_s3-3.0.0-0.i386.rpm case B-1 standalong linux use Geode frame buffer driver , so i guess the problem for case B-2 non-root user login will crash X
may be
on this package: ltsp_x336_fbdev-3.0.0-0.i386.rpm , please suggest 1. what to do next, 2. where to get the source code of ltsp_x336_fbdev-3.0.0-0.i386.rpm , thanks in advance. With best regards.
