Here some more information: (just for info: I went back to the orignal, open ubuntu drivers for the Radeon HD 7450A card replacing the AMD proprietary driver.Allthough this does not seem to have an effect on the bug)
1. Disabling PCI Devices: I disabled the PCI-devices: Web Camand Wireless Ethernet: echo 1 > /sys/bus/pci/device/$N/remove ... where $N is the slot you get listed with "lspci" The system still hangs (disabling other PCI-devices too would probably exclude further sources of bugs, but I am unsure what else I could disable) 2. Disabling Input Devices I disabled the Touch screen with: xinput set-prop ID 'Device Enabled' 0 .... where ID is the device numer you get listed with "xinput list" The system still hangs (disabling other input-devices too would probably exclude further sources of bugs, but I am unsure what else I could disable) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1178846 Title: 1002:6779 xorg hangs randomly with Radeon HD 7450A Status in “xserver-xorg-video-ati” package in Ubuntu: New Status in “xorg” package in Fedora: Unknown Bug description: Bug: Random freezes of xorg on freshly installed ubuntu 13.10. There does not seem any pattern when this happens. Usually takes 10-20min. There is no application running that requires special graphic ressources. Requires hard reboot. Mouse and keyboard hang. <ctrl> + <alt> + F1 does not work. Interesting is that this happens also with ubuntu 12.10, ubuntu 12.04.02 LTS and fedora 18. Hardware: HP Envy TouchSmart AiO PC - Intel Core i7 3770s - 8 GB DDR3-1600 - Radeon HD 7450A - Hard drive: 1 TB SATA - exact technical spec: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03683196&cc=ad&dlc=en&lc=en&jumpid=reg_r1002_usen_c-001_title_r0001#N1445 Further Info: 1. I ran "sudo dpkg-reconfigure xservers-xorg" to reconfigure the Xserver but this did not bring any change. 2. This sound like Bug #1077616 but I have a Radeon and not a Nvidia card.
