What is going on?!
Edit: More symptoms: I just tried to restart but didn't immediately respond to the Pluma "Save changes to ... before closing?" dialog, and it is now frozen. Seriously, what is going on here?
Edit 2: After a hard reset, I was reminded that panels are taking a lot longer to start once I've logged in. The desktop background comes in immediately, the desktop icons come in shortly after that, but the panels take about 10 seconds more to pop in. This has been true every time I've logged in since yesterday.
Also, I did grep error /var/log/dmesg and it only returned this:
Code: Select all
[ 36.575792] EXT4-fs (sda8): re-mounted. Opts: errors=remount-ro
Also, forgot to mention: I have GKrellM running and it doesn't show any spikes in CPU or memory usage when the window misbehavior starts.
Edit 3: I've also been having problems with Caja recently. It takes a looong time to show what's in a given directory, sometimes many dozen seconds before it will bring up the contents. Also, when I click on the Gnome program menu, the icons for the programs sometimes take a second or two to pop in. Could that all be related?
Edit 4: Trying to think of what's changed since last I booted into Linux, the only thing I could think of was that I installed the Windows drivers for my Logitech headset. That shouldn't affect the Linux workings of the device, should it? But I noticed that a) when I try to use the volume dial on the headset, it no longer functions right (seems to be trying to act like a mouse scroll wheel, rather than a volume control), and b) doing this multiple times seems to set off the bad behavior by Mate. Also, I had Terminal running Top when the latest misbehavior happened. This time, the CPUs started spiking, and Top showed that Mate-Session (I think it was) was using 99% of CPU time. Is my headset part of the problem somehow? I rebooted, this time with the headset completely unplugged from the machine. I'll see how it goes this time.
Also, when I rebooted, I timed how long it takes for various things to show up while the session starts. From the startup sound, here are the times:
Desktop background: 15 secs.
GKrellM: 20 secs.
Desktop icons: 50 secs.
Panels: 57 secs.
A full minute just to have panels? What is going on here?
