On beyond-linuxfromscratch we've been using an intel git pull from 20210222 with xorg-server-21.1.3 in our last release (11.1). For that we configured the intel driver with --enable-kms-only and also with --enable-uxa . In our 11.0 release we used the 1.20.13 server with that same version of the intel driver. If you are not familiar with BLFS, our releases list what we think works at that point. Obviously, people who care about security are expected to update certain things afterwards (e.g. xserver if running as root). The other thing about the intel driver is that most distros use the modesetting driver which is now part of the xserver (provided you supply the necessary dependencies). On my own old haswell with its integrated graphics I don't build the intel driver and modesetting works well. I recall that someone had issues in the past (maybe in late 2019) with modesetting on skylake, and I see that on my own skylake i3 I do build the intel driver because of that. I cannot confirm or deny that I _need_ that driver, the machine was used as a home server in 2019 and it's such a slow dog to build on that I've no incentive to see if it needs this (and slower now, of course, with retbleed). My last builds there were the versions mentioned above for our 11.1 release and they seem to work ok. Meanwhile, our development version of BLFS is currently using the 21.1.4 server with that same intel driver, but I have no idea if anyone has actually built that combination. ĸen -- It is very easy to get ridiculously confused about the tenses of time travel, but most things can be resolved by a sufficiently large ego. -- The Last Continent
