I don't want to reopen the thread, just add some new information. @Andrea: #15 #20 #39 The freezing problems you experience on the Amilo L7320 laptops are not related to the openchrome driver, it is a bug related to the APIC (or to a BIOS bug). It started with Ubuntu 10.10 (kernel 2.6.35). The clocksources are not detected or discarded by the kernel, and to work around this problem the kernel parameters [noapic, nolapic, nomodeset] can be used during boot time. (Btw I was also able to reproduce the problem on Fedora 15 and Debian Wheezy). For the Ubuntu 12.04 the nolapic parameter worked for me, for Lubuntu 16.10 and Lubuntu 17.04 (daily snapshot) nomodeset solves the problem. At the moment I am using Lubuntu 12.04 (kernel 3.2.0-120-generic):
cat /sys/devices/system/clocksource/clocksource0/available_clocksource tsc pit jiffies -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-openchrome in Ubuntu. https://bugs.launchpad.net/bugs/1205643 Title: VIA P4M800 graphics broken in Lubuntu/Xubuntu Saucy & 12.04.4 candidate Status in xserver-xorg-video-openchrome package in Ubuntu: Fix Released Status in xserver-xorg-video-openchrome-lts-saucy package in Ubuntu: Won't Fix Status in xserver-xorg-video-openchrome source package in Saucy: Fix Released Status in xserver-xorg-video-openchrome source package in Trusty: Fix Released Bug description: * Impact: - the driver doesn't work with the X.org version in 12.04 with the Saucy hardware enablement stack. * Test case: - try using 12.04 with the Saucy hardware enablement stack on a machine needing the openchrome driver. * regression potential: - check that xorg sessions work as they should. The patches have received testing in Debian/Trusty/Saucy and upstream, so presumably should be fairly safe. The number of people using openchrome is relatively small compared to the main X drivers, so the scope of risk is rather small here. ---------- Saucy Hardware Enablement Stack: https://wiki.ubuntu.com/Kernel/LTSEnablementStack ------- Please bear with me and read all of this. Since I can't get a working display in Saucy with that graphics chip I need to use this method to file the initial bug report, but I can provide info using a chroot or replacing the "quiet splash" boot parameter with "text" which takes me to a tty interface. I hope using the tty interface provided by using the "text" boot parameter I can use "apport-collect" to collect the info needed from an installed Lubuntu 13.10 but I won't do so until asked by a dev in case some "switch" needs to be set to collect the appropriate info. I also want to say that I'm fully aware that graphics chip is not supported by Ubuntu/compiz itself, or even GNOME's mutter window manager, but I think it should still work with the openbox, metacity, and Xfwm window managers ...... at least I hope so :^) So onto what actually happens. When I try to boot either Lubuntu or Xubuntu Saucy Alpha 2, either the live image or an installed version, I just get a frozen progress bar. So it's just 5 frozen dots on the screen. If I try booting through the recovery mode or otherwise trying to "startx" or "'sudo service lightdm start' I just get a blank screen. I can see the backlight is working but that's all. This is the specific hardware: VIA C7 CPU @ 1500MHz VIA CN700/P4M800 Pro/P4M800 CE/VN800 Graphics [S3 UniChrome Pro] (rev 01) VIA VT8233/A/8235/8237 AC97 Audio Controller (rev 60) Ethernet controller: VIA Technologies, Inc. VT6102 [Rhine-II] (rev 78) 1GB DDR2 RAM I did take a pic of the live image boot process while dealing with an unrelated d-i bug during Lubuntu Alpha 2 testing process: https://launchpadlibrarian.net/145894508/P4M800_xfreeze.JPG Now I'm wondering what else to say ............... the same Saucy images and installs work with two other totally different sets of hardware. I'm ready to roll up my sleeves to help gather any needed info. Thanks in advance.
