I've had this in Kubuntu (4.7.4) and now Chakra (4.8.0). So it seems KDE specific rather than distro specific - but who knows.

Simple enough. I get to the login splash and login box and get an immediate freeze, the mouse cursor freezes for between 60 - 90 seconds so you can't do anything. Then it stops, the mouse cursor frees up and I can sign in - drama over.

I've seen posts on google about this and never got a clear indication of a solution. Any ideas?

If you need further log information just say which ones and whether to use pastebin or not.

Thanks,

is this your bug https://bugs.kde.org/show_bug.cgi?id=220785 ?

if you run ls on /usr/share/apps/kdm/faces/ does the folder exist? does it have anything in it? if populated what are the permmissions?

as a quick fix I would guess you could place an icon file renamed to .default.face.icon in the folder, though a KDE upgrade will probably overwrite if not erase it

It's looking like it. In /usr/share/apps/kdm/faces/ there is one png icon that I remember selecting during installation (username/admin/password, etc). It's name is: [username].face.icon

Permissions: Owner = R&W / Group = R / Others = R

How about I delete the faces folder, will it get recreated with a default icon?

Thanks, btw.

as this is a system folder installed by a package it probably won't be recreated like a user folder/file. I would try copying the existing icon file and calling it .default.face.icon

Nah. Shame, I was hoping it would be a simple one to deal with.

it is maybe easy, as root

Code: Select all

cp  /usr/share/apps/kdm/faces/[username].face.icon /usr/share/apps/kdm/faces/.default.face.icon

edit: left the "n" out of the destination file

I see what you did, and I see the icon as .default.face.ico next to the original, but on reboot it doesn't seem to make any difference.

I don't get this problem simply logging in and out either, btw. Only on restart / cold boot.

sorry, missed an "n", file extension should be "icon"

should be:

Code: Select all

cp  /usr/share/apps/kdm/faces/[username].face.icon /usr/share/apps/kdm/faces/.default.face.icon

Even with the "n" .icon extension it still hangs for some reason. I'll give it this, it's consistent.

One thing you could try to do is use gdb to get a backtrace once it has frozen. Debug symbols, and the ability to switch to a VT will be needed here.

Ctrl+Alt+F1 for VT, right? I can't do it during the freeze so obviously directly after, right? Turns out I've got GDB already installed. What debug symbols package do I need? kde workspace debug?

I've got the gdb man so I can give that a quick go over.

The kde-workspace debug packages should be sufficient as far as I can tell.
If you are unable to change VT once the login freeze has kicked in, it may indicate that your system is having some other problems at the graphics or kernel level causing this freeze.

Unfortunately the only way to know for sure is to use another system via SSH to attempt to debug the issue.

Definitely no keyboard response during the freeze. But then the KDM log makes mention of the keyboard but states it's not fatal.

But I'm still puzzled as to why Kubuntu had the same symptoms and others have reported it over a long period of time.

This is more or less repeated throughout a long log:

It appears to be failing to load your keyboard layout. Please make sure they are installed if needed.

As far as i know I've got everything I need, I've got: xf86-input-keyboard 1.6.0-2 (XOrg keyboard input driver) and xkeyboard-config 2.4.1-1 (X Keyboard configuration files). And under system settings >> Layouts >> English (UK, extended WinKeys) label = gb
