« : 26.06.08 - klo:09.15 »Nyt meni mystiseksi. Lakkasi toimimasta koko kosketusnäyttö, kynällä tai ilman. Vaikea keksiä syitä, paitsi se unofficial patch, jolla suspend-ongelmaa korjasin. Ideoita mistä kohtaa ongelmaa voisi debugata?
You know that the touchscreen stops working after suspending, right? Restarting X restores functionality. I am working on a solution but so far it seems to be something that we will just have to wait out while they update the X-server to a yet unreleased version.
What happens is (not 100% on the details but the general idea is right) that when you suspend the kernel disconnects all USB devices including our wacom touchscreen and then it reconnects them all on resume, but X notices this and removes the input device and since X doesn't do hotplugging (it does but there are some quirks and most distros have it disabled) it won't reconnect it on resume. Thus we have no tablet on resume and a restart of X fixes it.
Edit: Wait, what patch? If it has done something to X and/or X input drivers you might have to reinstall your tablet drivers. /var/log/Xorg.0.log should tell you what has happened.
EditEdit: Thats what i get for writing posts before drinking my morning coffee.
