I have the same problem with my LTSP setup, i read somewhere that this could be the case when videoram isnt properly detected by xorg. I've put a hardcoded value for videoram i my lts.conf and going to see what happens.
My setup is: LTSP-server: HP ProLiant ML110 G5 Dual-Core Intel® Xeon® Processor X3065 4GB RAM PC6400 DDR2 4x 250GB SATA (2x mirror RAIDs) Embedded NC105i PCI Express Gigabit Server Adapter LTSP-clients: HP Compaq t5725 Thin Client AMD Geode™ NX 1500 1.0 GHz 256 MB DDR SDRAM 512 MB Flash RAM SiS741 CX 16 MB and HP Compaq t5135 Thin Client 400 MHz 128 MB DDR SDRAM 64 MB Flash RAM Intel UMA 16 MB -- Ltsp 5 freezes sometimes when I try to close a window! https://bugs.launchpad.net/bugs/122646 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
