Bug has been already fixed on latest upstream, but it is pretty alive on latest amd64 gentoo stable (2.1.1). I've done nothing but backporting the bugfix to this version.

Hi Alessandro,

The current stable version of the Intel driver is a dead end and we're in the process of stabilizing a much newer version of the Xorg stack.

That's why I strongly advise you to try the keyword list from bug #251832 so you can update your Xorg to what will become stable Real Soon (tm). It looks to me that the bug is fixed in the latest ~ version of the intel driver (2.6.3) and if it isn't, I would rather fix it there rather than 2.1.1.

If you have any issues with the update, please don't hesitate to open a new bug.

Thanks

yes, the issue has been solved in 2.6.3 (the originator of this backport, as I said)

...and yes, I already tested it yesterday, right before doing the backport :-)

Unfortunately I cannot be as enthusiastic as you about the New Stuff (tm). The update took me about a day of hassles, which end up into a barely usable X11 with major keyboard issues (e.g. keys stuck unexpectedly, variable repeat rate, etc), minor synaptic issues (e.g. best effort tapping) and a severe frame drop in DRI rendering. Now, it is quite possible that I've missed something during the upgrade and that all that crap goes away doing the Right Thing (tm), but at the moment I'm quite happy with the old stuff. :-)

Cheers,
Alessandro

Thing is, our goal is to get rid of the old stuff.

Please do try to go to 1.5.3 and don't hesitate to file bugs or ask for help in #gentoo-desktop on FreeNode.

Thanks

I completely agree with you on this matter. I run E17 on my laptops since the beginning, ie. when ebuilds had yet to come, but this time I fear there are too many issues to solve and I've almost no time to tackle them. :-(

Yeah, I know. Gentoo people is great on this matter! :-) As said, I already tested it yesterday; above you can get an idea of the encountered issues. I had little time to research, but I suspect they are mainly related with HAL (IMHO, of course).

Ciao.
