tseliotricotz: hey, just FYI, I've just uploaded a new libvdpau, which I merged from debian12:51
alkisgtjaalton: hello! Regarding LP: #1815172, all schools close for the summer, so I only have the i915 PC in my office to test with, but I'm not sure if it's affected or not (I was testing with 64bit at the time and it wasn't):18:24
alkisg00:02.0 VGA compatible controller [0300]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)18:24
alkisgSubsystem: Gigabyte Technology Co., Ltd Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [1458:d000]18:24
ubottuLaunchpad bug 1815172 in mesa (Ubuntu Bionic) "[bionic] drm/i915: softpin broken, needs to be fixed for 32bit mesa" [High,In progress] https://launchpad.net/bugs/181517218:24
alkisgWould it make sense to test there?18:24
tjaaltonalkisg: I was able to repro after all18:26
tjaaltonam writing a comment now18:26
alkisgAh great, thank you18:26
tjaaltonwas kinda hard to find hw for it.. had to install to an external ssd and use a t470s, everything else I tried before that was too old18:28
tjaaltonor didn't support legacy boot at all (hello intel)18:28
tjaaltonbut, I missed the bionic kernel respin by some hours18:29
alkisgI arranged to have remote access in many school just for things like these, where bugs only happen in certain hardware... but I'd have to wait for September when they open again :/18:29
tjaaltonno worries18:32
tjaaltonI should have a setup for this :P18:32
tjaaltonan external disk is handy18:33
tjaaltonthe internal one was partitioned for gpt and whatnot, couldn't install a bootloader on it, and booting via the installer ended up in initramfs18:34
tjaaltonstill, I don't get it why folks run 32bit on skylake and up :P18:39
tjaaltonat least that will be a thing in the past come next year..18:40
alkisg(09:39:36 PM) tjaalton: still, I don't get it why folks run 32bit on skylake and up :P ==> that's my "fault" for developing ltsp, and allowing a single installation to be used as a template to netboot any number of clients18:45
alkisgSo since the clients are 32bit, the server needed a 32bit installation18:45
alkisgThe plus side is that it's so easy, that 1000+ schools managed to do it; the negative side... you know ^ :)18:45
alkisgSo now I'm implementing an easy way to offer both 64bit (using the server as a template) and 32 bit using a virtualbox vm as the template18:46
alkisgIt's possible to install grub-pc (bios) in gpt, but it requires a special grub-boot partition18:47
alkisgI have my own PCs like that, bootable in both uefi and bios modes, for easy testing18:47
tjaaltonah18:49
tjaaltonI need to test that18:50
tjaaltonthe installer did complain about that18:50
alkisghttps://termbin.com/xomb => these are the grub packages needed to have a dual efi/bios boot18:55
alkisggrub-pc conflicts, so I remove it, but keep grub-pc-bin18:55
alkisgOther than that, it makes no difference if you start with uefi install or bios install, the end result is the same18:56
tjaaltonok, cool18:57

alkisgAnd these are the boot partitions involved, i.e. efi and unformatted grub-boot18:57
tjaaltongot it19:12
