KDE hangs on lock screen, after after waking up

Sat Jan 18, 2014 3:02 pm
Hi, I have following problem.
When I suspend my laptop (by closing it, for example), after turning waking it up, I see usual lock screen, where I need to type in my password to get back to work.
However, I need to wait, because it's not responsive for ~15-20 seconds so I can't type a password.
Anyone had this problem and solved it?

I don't know which output will help you resolve my problem, so I wait for suggestions.
I also should mention, that currently I have this problem on Arch Linux (up-to-date), but I also had it previously on ubuntu.

sounds like some I/O timeout (network, dbus, HDD)
"dmesg" or ~/.xsession-errors might know more about it.

try suspending compositing before STR (Shift+Alt+F12) if that helps, it's pot. the graphics driver. -> nvidia?

Yes, it's nvidia, but disabling effects didn't help.
It looks like my hdd is loading very slow (see bolded lines in dmesg).

What can I do with that? I have SSD for the OS (/dev/sda) and HDD (/dev/sdb) for usual storage (music, ebooks, steam library etc.).

dmesg from waking up:

Re: KDE hangs on lock screen, after after waking up

Aaa.. only 15 seconds - not much time at all ... ;-)

Time matches nicely, so this will be it.
You can pot. alter power saving behavior in BIOS/EFI and there may also be hdparm/sdparm calls in pm-utils hooks (/etc/pm/* & /usr/lib/pm-utils/*)

However that's really a lot of time, did you recently perform a SMART check on the disk? (whether it's healthy)
