More testing: 1. laptop-mode only worked fine in the casper chroot as long as proc was mounted. If not, it will report no laptop, since it doesn't find /proc/acpi. Then xresprobe will use ddc and return: laptop: ; ddc: yes attempting DDC detection raw timings - 1680x1050 id: res: 1680x1050 freq: disptype: crt
1b. tried dpkg-reconfigure with this and continued booting. Now X failed and I got the failsafe X configurator (which wouldn't let me choose 1680 resolution even if I picked "1680 LCD screen", but that's another story). But I eventually got a lockup (compiz?unionfs?) Looking at the old xorg.conf it seems like dpkg-reconfigure had picked vesa (maybe because it didn't see the ati card without /proc). I guess casper mounts /proc before configuring X so all the above is not a practical problem. 2. tried booting up normally, then dpkg-reconfigure. I got the same xorg.conf as the one casper makes. Good. That was half of the original bug report solved. 3. I then modified laptop-detect to always return false, and ran dpkg-reconfigure. I got the same xorg.conf as in (1b) except now with ati and it worked. It had added Modes "1680x1050" and correct sync ranges to xorg.conf (and omitted synaptics), compared to the one in (2). 3b. Tried xresprobe, which then will always use ddc and return "1680" whether I force crt, lcd or laptop. FWIW, I also tried with the new xresprobe 0.4.24ubuntu5. Same results. I can provide logs and debug output from most of the tests. (After all this testing, my video card is a little fscked up after warmstart and I am typing this in vesa and stretched widescreen. I'll have to unplug battery and power to get ati to work right again I guess.) So the conclusion is still the same: xresprobe fails, and that's ok for the new ati driver. -- fails on ATI Mobility X700 (Acer TravelMate 8100) https://bugs.launchpad.net/bugs/57525 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
