[08:01] <apw> killall (N,BFTL), we were only very briefly on 3.18 in vivid and only produced kernels which carried interally 3.18.7 before we switched to early 3.19 kernels
[14:26] <enyc> Hrrm....
[14:27] <enyc> ubuntu 21.04 on asus x201e-netbook  (something like intel integrated graphics on core-i3 2nd-generation),  is experincing blackscreens  w/ ubuntu 21.04 and default 5.11 kernel including latest -proposed update version
[14:27] <enyc> workaround is "nomodeset"  but then get acceleration warning etc.
[14:28] <enyc> manually installing debian-provided kernel 5.10.0-6 LTS/bullseye kernel image package (no headers)  and booting with that works around issue
[14:28] <enyc> [yes yes, technically using ubuntucinnamon 21.04 variant but I really really don't think this is issue, will blackscreen loading lightdm before even booted into gui]
[14:29] <enyc> any $helpful suggestions how to further debug this, report right bugs, ...
[14:29] <enyc> (or indeed, existing bugs I haven't found yet which may be spot-on) ?
[14:30] <enyc> NB: System graphics working fine with  Mint 20.1 (20.04 lts based),  MX19.3 and MX21 testing (deb 10 and 11 based),  devuan chiamera (deb11 based)...  its' just the 21.04 test-install thats' not behaving with blackscreening X11!
[14:30] <enyc> once blackscreen comes seems to be impossible to get rid of without reboot even if kernel clearly still alive as  able to alt+sysrq+ S,U,B  to reboot
[14:35] <enyc> I believe' .early-on, 21.04 installer was OKAy but after  first updates then started breaking!
