autologin issue after last april kernel upgrade

Postby freespirit » 2018-05-05 08:16

i'm running stretch xfce, i had autologin on, and worked like a charm, after 04/29 kernel update, just after autologin the screen go black for 50 seconds then boot normally, or go on if i move the mouse, if i boot the system keep moving the mouse everything go smooth, i've searched a solution on the web found nothing i decided to upgrade to buster, everything went fine and with 4.15 kernel autologin was perfect, today linux 4.16 (04/29) was up i've upgraded and the problem is back, i've downgraded back to 4.15 and problem is gone.
i think somethig on 04/29 patch on both kernel give me some kind of issue, but i don't know how to figure it out, any suggestion?

i've made another trial, with buster also if i disable autologin, after i digit the user and password i see the debian desktop image but it stuck and go on desktop after a while only if i move the mouse

so:
xfce stretch autologin next to last kernel: is everything ok
xfce stretch autologin last kernel: after login phase screen become black and after 40 seconds go on desktop, alternatively if i move the mouse in that phase everything is ok
xfce stretch no-autologin: everything is normal
xfce buster autologin next to last kernel: is everything ok
xfce buster autologin last kernel: after login phase screen become black if i do not move the mouse it hold on black forever, if i move the mouse take more than stretch to go on desktop
xfce buster no-autologin last kernel: after login phase i see the debian lightdm greater image, if i do not move the mouse nothing happen, if i move it, it take a while to go on desktop

when i revert to the next to last kernel everything work like it should be


everything else work fine, but i can't understant where is the problem, i also have installed on a VM xfce stretch setted almost like the same my machine but i cannot reproduce the issue

Several of us had the same problem. Has to do with low entropy, whatever that means, and the system runs out of random numbers during boot. Installing haveged fixes it, but there is now another kernel update with the problem fixed. Patch on a patch? Anyway it works now, without the extra haveged package.

...so just in case that wasn't clear enough:
do another
Code: Select all
apt update
apt upgrade

and it should be fixed again, no need to install any extra packages.

Just to note:

The haveged package was a workaround rather than a fix, urandom != random
