LTSP-4.2

Problème de crash X.org

Sur un terminal LTSP, causé par le fichier '/tmp/var/log/Xorg.0.0.log' qui devient trop gros et prends toute la place.

Ce fichier grossit à cause de ce message d'errreur, répété sans arrêt:

(II) TRIDENT(0): vgaHWGetIOBase: hwp->IOBase is 0x03d0, hwp->pIOOffset is 0x0000

Problème réglé en modifiant le code source du driver trident.

What should I do if I have poor quality sound (pops, clicks and squeaks) - particularly when dragging or scrolling windows?

This is caused by X writing blindly to the video card's instruction queue without checking to see if the queue is full. This will lock the PCI bus for about 40 - 50 audio cycles, causing pops, clicks and squeaks. The via82cxxx_audio driver is still somewhat fragile, so it is possible that some applications will fault ungracefully if the bus is disrupted badly enough (e.g. with SDL applications). You can make X play nicely with the PCI bus by adding Option "PciRetry" "true" to the "Device" stanza. Nasty pops and glitches will go away, and system stability will be much improved.

Message d'erreur du terminal LTSP:

 /bin/sh: can't access tty; job control turned off

Solution: Contrairement à LTSP-4, il faut éliminer l'adresse IP de l'option 'root-path' du fichier /etc/dhcpd.conf.

Si vous n'arrivez pas à vous authentifier, et que le serveur reporte ce message dans /var/log/auth:

 (pam_unix) check pass; user unknown
 (pam_unix) authentication failure; logname= uid=0 euid=0 tty=tty1 ruser= rhost=
 FAILED LOGIN (1) on 'tty1' FOR `UNKNOWN', User not known to the underlying authentication module

Solution: Éditer /opt/ltsp/i386/etc/ssh/ssh_config et activer l'option:

 PasswordAuthentication yes
