I used to mount drives and stuff in /mnt all the years. Now I just stumble to see, that some cgroups directory is in there. Is this normal? Is this to be expected?
View 1 RepliesI have played around a little bit with CGROUPS and the fair group scheduler ( using kernel version 2.6.31). When you have CGROUPS in a flat structure, with only one layer from the root-cgroup, everything works as you might expect when setting the cpu.shares parameter, i.e. a fraction of the total. But when I experimented with having deeper levels of CGROUPs it did'nt make any sense sometimes. For example, I had one CGROUP with the maximum number of shares (260000 something) , and two childgroups with quite little shares, 5000. Then I created some cpuhogging processes ( while(1); ) and put most of them in childgroups and one in the parentgroup. The logical thing would be if the parentgroups single process took almost all CPU-time, as it had the maximum number of shares, but instead the processes in the childgroups got the most CPU-time.
I have tried to figure out how it works by looking at the source code, but I can't really understand it. How does the hierarchical structure of the cgroup-tree interact with the flat aspect of it, i.e. siblings? Or do I misunderstand the whole concept?
I recently switched from Ubuntu Maverick 32-bit to 64-bit so I could compile Android's latest revision, Gingerbread.
Everything went pretty smoothly and I managed to fix most issues that was caused due to the switch.
But each time I open terminal, the following error shows up:
Code:
mkdir: cannot create directory `/mnt/cgroups/cpu': Permission denied
bash: /mnt/cgroups/cpu/19088/notify_on_release: No such file or directory
bash: /mnt/cgroups/cpu/19088/tasks: No such file or directory
I've tried manually creating that directory as root but the error remains.

I experience this since kde 4, but it never really was that bad because once in a while on updating kde I also deleted the .kde folder in my home-folder and everything was fast again.
But I haven't done this for a while now and kde take really long to load. Is there any folder to clean up there without deleting the whole .kde-folder and loosing all my settings again?

Look at the screenshot, I have only one file in trash but AWN and Docky counts 47+1 items. When it's empty it counts 47, and there's no way to really empty. But files are really gone. It doesn't happens with Cairo Dock (I don't know why).

View 3 Replies View RelatedSo the other day I got myself a nifty ThinkPad x100e. I immediately removed windows 7 started, and installed UNR 10.04.It has a 250GB hard drive, which I decided to partition, so that I can keep all my stuff on the new partition, and then a fresh format or install of the OS would be easier.After struggling to take ownership of my own damn partition after creating it and mounting it, I discovered a rather interesting problem. I KNOW the partition is empty, but when I right click and go to properties, it says that 10GB is already used? This is rather confusing to me

He tried to do a regular upgrade and after it installed his screen had wallpaper and that's it. No icons or task bar or anything.

View 9 Replies View RelatedI installed Natty in a VirtualBox VM (running in XP), and all I see is an empty Desktop with background. No Launcher or anything else to run anything.
It is obviously running, because I can right click on the desktop, create a folder and navigate round. If I navigate to an application I can run it.
Rebooting to Classic works (if maybe a little slower than 10.10).
I wanted to try Unity, and assume it is trying to run.
I have an empty X session running, and I want to run kde inside it. I can run whatever software I want in it, actually (well, I can't move the windows and so, but that is normal), but for some reason, kdm doesn't work. What I have is a X display and a xterm inside.

I have removed the trial of win 7 and want to use the empty space for Ubuntu 9.10, [46gb]. Opening disk utility shows 60gb hard drive, divided into system reserved 105mb, 46gb file system [Linux ext4 [version 1]], 13gb extended [contains no logical partitions], 13 gb [Linux ext4 [version 1]], 617mb swap space.Because I have given the 46gb space the same name as the 13gp space i.e. [Linux ext4 [version 1]],will this now be used By Ubuntu for data storage or do I need to do a complete re-install?

View 2 Replies View RelatedSince I had updated to Lucid, I'm having some trouble with running my laptop on battery. It usually turns off when the battery notifier is still at 13%~18% (it is not shutting down, it is like when your battery runs out of energy). First I had thought that was a problem with the notifier and I was missing when the battery had no charge, but I kept looking at the notifier and suddenly when it had reached 15% my laptop just went down, without saving any job.
I've just upgraded to Lucid Lynx, running on a HP Pavilion dv4-1123us with 2.00 GHz Intel Core2 Duo T5800, 4GB RAM.
The battery is a 6-cell Lithium-Ion that came with the laptop.
I'd bought it about 1 year ago.
