[Desktop-packages] [Bug 1623969] Re: Cannot log in to kubuntu after update (Intel graphics + ksshaskpass)
Alan Robertson, thank you for reporting this and helping make Ubuntu better. To clarify, if you boot into the kernel prior to the update, does this issue go away? ** Tags added: bios-outdated-2202 regression-update ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1623969 Title: Cannot log in to kubuntu after update (Intel graphics + ksshaskpass) Status in xorg package in Ubuntu: Incomplete Bug description: I just took some updates to a number of graphic libraries on 16.04, and now I can't login to kubuntu.

[Desktop-packages] [Bug 1623969] Re: Cannot log in to kubuntu after update (Intel graphics + ksshaskpass)
Hi Christopher M. Penalver (@penalvch), I have tons of old kernels to choose from. What one would you like for me to try? Here are the choices: vmlinuz-3.19.0-28-generic vmlinuz-3.19.0-41-generic vmlinuz-4.2.0-36-generic vmlinuz-3.19.0-30-generic vmlinuz-3.19.0-42-generic vmlinuz-4.4.0-22-generic vmlinuz-3.19.0-31-generic vmlinuz-3.19.0-43-generic vmlinuz-4.4.0-24-generic vmlinuz-3.19.0-32-generic vmlinuz-3.19.0-47-generic vmlinuz-4.4.0-28-generic vmlinuz-3.19.0-33-generic vmlinuz-3.19.0-49-generic vmlinuz-4.4.0-31-generic vmlinuz-3.19.0-37-generic vmlinuz-3.19.0-51-generic vmlinuz-4.4.0-34-generic vmlinuz-3.19.0-39-generic vmlinuz-3.19.0-56-generic vmlinuz-4.4.0-36-generic By the way, I did try this before, and I think it worked, but I had trouble with USB devices afterwards (or so I remember). Since my mice are USB, that was a problem. So it would be helpful to me for you to suggest which kernel you would like for me to try... Something I forgot to say... When I remove all the .kde stuff and it boots up correctly (but crippled due to all my config missing), then the fifo underrun does _not_ occur. It occurs only once per login. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1623969 Title: Cannot log in to kubuntu after update (Intel graphics + ksshaskpass) Status in xorg package in Ubuntu: Incomplete Bug description: I just took some updates to a number of graphic libraries on 16.04, and now I can't login to kubuntu.

I'm unsure if I understand the above but I have the same problem on a fresh install of kubuntu 16.04.1 and it occurred after I did a reboot just after changing my user password via the user manager in the system settings. Having switched to the tty1 command line from the frozen kde login I noticed that ecryptfs-mount-private still only accepted my old user password to unlock my home folder. When I changed the user password back to the original one, kde login worked again.

my solution at:
kubuntu 16.04 SDDM login screen hangs

Recently I encountered this problem with kubuntu 16.04 SDDM login screen
hangs. The issue occurred after I installed kubuntu 16.04 on an Intel
i7-7700k with Intel 630 HD graphics and then updated to the latest
packages.
I was able to login using the workaround of using Ctrl+Alt+F1 to get to
a text console and then Ctrl+Alt+F7 to get back to X and the logged in
session.
I stumbled upon a fix to the login hang while I was working to get rid
of a screen tearing problem. The fix involves changing the compositor
rendering backend from XRender to OpenGL.
More specifically to address the hang on login and problem with screen
tearing I did the following:
FIX SCREEN TEARING AND LOGIN HANGING
A) Start K -> Settings -> System Settings
Under Hardware section
Double-click Display and Monitor
Choose Compositor on LHS
Enable compositor on startup: Checked # was checked
Rendering backend: OpenGL 3.1# was XRender
OpenGL interface: GLX
Tearing prevention ("vsync"): Full screen repaints # was Automatic
Ignore message "Full screen repaints" can cause performance problems.
Click Apply

Bug description:
I just took some updates to a number of graphic libraries on 16.04,
and now I can't login to kubuntu. The symptom is that it takes my
password on the greeter screen, but never updates the screen after
that.
The messages include these possibly related kernel messages:

Here are my most recent updates. The problem started after I rebooted.
