LTSP
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.
