bom dia, configurei minha maquina pra atuar como um sistema multiseat ( uma maquina com 4 monitores, teclados e mouse ) esses sistema tem 4 placas de videos e usei o xephyr seguindo o seguinte tutorial http://netpatia.blogspot.com/2006/09/multiseat-computer-with-ubuntu.html
e em anexo tá o script q usei pra chama o X pelo gdm (Xephyr.sh) e os demais arquivos de configuração. tudo estava funcionando bem até q conforme os usuários estão usando o gnome o gdm reseta, encerrando o X e voltando pra tela inicial de login do gdm. Nao aparece nenhum log de erro /var/log/Xorg.0.log e nem no syslog. nao consigo entender o motivo disso, as vezes demora 30 minutos pra acontecer, ou menos. A config da minha máquina é: AMD Sempron 1833.216 MHz 1 GB de ram placa ASUS com 5 slot PCI e um AGP placas de video: nVidia Corporation NV5M64 [RIVA TNT2 Model 64/Model 64 Pro] AGP Trident Microsystems TGUI 9660/938x/968x PCI S3 Inc. ViRGE/DX or /GX PCI Trident Microsystems TGUI 9660/938x/968x Agradeço a ajuda!
