I upgraded the kernel to linux-image-3.8-trunk-amd64 from Debian experimental and, so far, the video symptoms haven't recurred.
just noticed your reply, hadn't seen it earlier. have you noticed any oddities with USB on the 3.8 kernel? the reason i ask is that every debian kernel package i've tried after linux-headers-3.7-trunk-amd64 3.7.3-1~experimental.1 results in broken USB support on both my main desktop machine and my mythtv box. i.e. with 3.7.3, USB works. >= 3.7.8 it doesn't. I never tried 3.7.[4567] so i have no idea if they have the problem or not - i went straight from 3.7.3 to 3.7.8 and then tried 3.8 before reverting to 3.7.3 this is particularly annoying on the myth box because the tuner cards are USB-on-a-PCI-card (with a VIA USB chip). the USB keyboard/mouse work but the tuner cards don't. on my main desktop machine, the USB keyboard & mouse also work but it won't recognise a USB HP printer when i plug it in...doesn't even notice that it has been plugged in. this may be a complete red-herring, but the only USB thing both machines have in common is that they both have Dell Multimedia keyboards plugged into them. I bought a bunch of them from a swap meet a few years ago because it was the kb i used at work and i got tired of fat-fingering the wrong keys when switching between work and home. they're not bad keyboards, not great but better than the typical cheap junk keyboards, but I have noticed weird problems with them in the past (e.g. until recently, maybe 3.2 or 3.5 or the 3.7 kernel, they'd freeze and need to be unplugged and plugged back in after a reboot...something in the linux kernel initialisation confused them. it was linux-specific because my gaming machine which is dual-boot linux & windows 7 had the problem when booting linux but not booting win7). i think the problems are due to the weird USB hub they have built in to them. craig -- craig sanders <cas@taz.net.au>
