problem SOLVED (was: Re: more Thinkpad T60 X/video woes (5.0-stable amd64))
In a thread back in November 2011, http://marc.info/?t=132173453400070r=1w=1 I reported intermittent kernel/X hangs (usually under near-idle loads) on a Thinkpad T60 widescreen laptop (alas I misspelled the name as Tinkpad in the Subject: line) running 5.0-stable amd64. My full dmesg is given in the first message in that thread, http://marc.info/?l=openbsd-miscm=132105242827683w=1 along with various other (hopefully-)relevant information. There's also more information on the problem symptoms in my later messages in that thread, http://marc.info/?l=openbsd-miscm=132103762123592w=1 http://marc.info/?l=openbsd-miscm=132137790200900w=1 http://marc.info/?l=openbsd-miscm=132813757309520w=1 I'm pleased to report that as of 5.1/amd64 (either -release or -stable) the problem is solved -- the default autoconfigure-everything X works fine, with no crashes or hangs and full video acceleration. My thanks to all who contributed ideas in the thread (and to all the developers for a *great* 5.1)! ciao, -- -- Jonathan Thornburg [remove -animal to reply] jth...@astro.indiana-zebra.edu Dept of Astronomy IUCSS, Indiana University, Bloomington, Indiana, USA Washing one's hands of the conflict between the powerful and the powerless means to side with the powerful, not to be neutral. -- quote by Freire / poster by Oxfam

Switching between GENERIC.mp and GENERIC made no difference to this problem. My original reports were with X autoconfiguring (i.e., /etc/X11/xorg.conf did NOT exist), using the Radeon driver: % dmesg|grep vga vga1 at pci1 dev 0 function 0 ATI Radeon Mobility X1400 rev 0x00 wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) radeondrm0 at vga1: apic 1 int 16 Since I don't actually need/use accelerated 3-D video, I've tried to switch to the generic VESA X driver. Alas, I haven't been able to construct an /etc/X11/xorg.conf which successfully uses the VESA driver at the full (15.4 widescreen) hardware screen resolution of 1680x1050 pixels. (None of my attempts would go above 1400x1050 pixels, stretched in a horribly ugly way to fill the screen.) As a last-ditch measure to try to get a reliable computer, I've tried disabling ALL video acceleration using the xorg.conf given below. This works -- I've had no more hangs in the 2 months I've been using this configuration (now with 5.0-stable GENERIC.mp), whereas before I was getting multiple hangs/week. Alas, this has come at the price of painfully slow scrolling in xterm, painfully slow window drags, and general video performance that reminds me of that 8 MB Sparcstation SLC I remember using back around 1990 or so. :( :( So... questions for the list: * Can anyone point me to a working xorg.conf to use the VESA video driver on a T60 @ 1680x1050 pixel resolution? * Can anyone suggest a better fix or workaround for my X hangs? Loosing 3-D acceleration is no problem for me, but 2-D acceleration would be nice... * If I do switch back to the Radeon driver, and the hangs reoccur, is there any information I could gather from a hung machine, and/or any logging I could switch on before a hang, that would be useful in further diagnosing the problem? * Starting from a cold boot, my current xorg.conf (given below) doesn't work -- X is unable to properly initialize the video, resulting in a screen display that's vaguely abstract-art bars of white pixels scattered around the screen, with no X cursor visible. So, right now, after each cold boot I first start X with an xorg.conf in which the line Option NoAccel# [bool] is commented out (with thie xorg.conf X starts fine, but is vulnerable to crashes), then immediately shut down X, then restart with the no-acceleration xorg.conf (the one given below). This procedure works, but is awkward.
