Ubuntu :: Ram Seems To Be Accumulated Until Reboot?
Oct 6, 2010
I am posting here rather than in the Maverick Meerkat section because this happened in Lucid too.I have just rebooted my system and ram usage is at 16% (of 2GB) whilst nothing is running other than desktop and Compiz. However if I leave the system running for 2 days (just using suspend from time to time) the ram usage will increase to 25 or 26% at idle.This will reduce again to 16% after a reboot.In short it seems that some processes are not fully releasing the ram they use and there is a build up of wasted ram.Does anybody else notice anything similar? Does anybody have any suggestions as to how to nail down the offending processes?

I am using sda1 as /, which is a bootable drive. I do not know if my problem is that I did not create a /boot drive. After removing the iso dvd, I tried to reboot and I get this back: -bash: /sbin/reboot: input/output error Then it returns me to the terminal prompt.

Further to this LQ thread which Tinkster solved by suggesting the last command (thanks Tinkster) I have been exploring last -x reboot and have found that the reported duration is incorrect for the last reboot and shutdown when a old wtmp file is used. Not having a record for the following shutdown, last assumes that the system has been up until the current time and similarly for the shutdown.
The output comes in time order, latest first, each line showing the time of the reboot and the uptime from then to shutdown. Using last -x reboot shutdown to show the shutdown time, here's an illustration
Code:
shutdown system down 2.6.29.6-smp Sun Mar 7 15:35 - 03:02 (11:27)
reboot system boot 2.6.29.6-smp Sun Mar 7 09:35 (05:59)
09:35 until 15:35 is 05:59.
When the uptime exceeds 24 hours it is shown as (<days>+<hours:minutes) like this
Code:
shutdown system down 2.6.29.6-smp Sun Feb 21 12:39 - 13:20 (00:40)
reboot system boot 2.6.29.6-smp Sat Feb 20 09:39 (1+02:59)
09:39 until 12:39 the next day is 1 day 02:59.
The time in parentheses at the end of the shutdown lines is normally the time until the next shutdown.
So far so good. The incorrect output is for the last reboot and shutdown of an old wtmp file. Here's the output of last /var/log/wtmp -x reboot shutdown; last -f /var/log/wtmp.1 -x reboot shutdown
Code:
[snip]
reboot system boot 2.6.29.6-smp Fri Mar 12 07:42 (01:54)
shutdown system down 2.6.29.6-smp Fri Mar 12 01:31 - 09:37 (08:05)
wtmp begins Thu Mar 11 08:25:26 2010
[snip]
reboot system boot 2.6.29.6-smp Wed Mar 10 14:12 (15+01:42)
shutdown system down 2.6.29.6-smp Wed Mar 10 12:41 - 15:54 (15+03:13)
[snip]
The boot started at "Wed Mar 10 14:12" which had an actual uptime of 1 day 11:20 is reported as 15 days 03:13 which is the time from then until the last -f /var/log/wtmp.1 -x reboot shutdown command was issued. The time from shutdown to shutdown is similarly affected.

I use a few different hard drives that I plug into one PC instead of partitioning, since it causes problems. I plugged in my Ubuntu 9.10 64 bit and it booted up in 1024x768 instead of 1280x1024 which is the default resolution for this monitor.Why would it change when it's been 1280 x 1024 everytime but this time? When I check the display settings it doesn't even have 1280x1024 anymore?

I'm using 10.04. I had sound this morning, and after a reboot ... no sound. When I click on the speaker in the panel and choose "Sound Preferences..." and then choose "Hardware" it's blank. In the "output" tab all I have is "Dummy Output" (it's stereo at least). I don't remember updating Ubuntu since the morning, but I might have. If I type in "pulseaudio" into terminal I get this:

I'm running 9.10 64 bit. Yesterday, I installed some updates (through update manager) and, upon reboot, I go into the CLI and am unable to get to the GUI.
Things that I've tried:
1) Reverted back to the most basic xorg.conf file.
Quite often (I'd say 50% of the time) when I install updates that ask me to restart my computer, I just get a black screen upon reboot. Normally, I can go in with the live cd, revert to the oldest xorg.conf file, reboot, install drivers, reboot again, and I'm good.
Not so much this time. Reverting back to the oldest file didn't change anything - I still boot into the command line.
2) Code:
This causes my computer to flash black (like x is starting) but then the command line reappears with a bunch of messages of the form
Code:
Where the "x" stand for random numbers. These messages are followed by the following:
Code:
waiting for X server to shut down ddxSigGiveUp: Closing log
I get these messages regardless of the version of xorg.conf I am using.
I've also tried
Code:
and
Code:
But neither do anything (the first tells me to try the second, and the second gives me a bunch of random errors that I don't feel like reproducing, but will try.
3) Code:
This does absolutely nothing. I get no output at all. It doesn't ask me any questions or produce any error messages. I just get the prompt again on the next line.

I have a PC running 10.10 Gnome 2.32.0 Kernal 2.6.35-24-generic-pae, i686
I am using /dev/sda3 on my primary hard drive (200Gb) to run my Kernal I have all my documents stored on a second, 500Gb hard drive: sdb2

a. How it got there
b. Could it be the cause of the problems
c. How I remove it.

Why my pc freezes upon reboot once in a while, especially after certain updates? It never happened under Vista. I'm with Ubuntu 10.10 since October, never used Linux before. I think it's a bug in Maverick but I'm too lazy in reading the very long sticky! What happens at those very few times is a normal reboot, but a few seconds after a gradual and then complete freezing, you would have time to click the firefox icon but it will never open. Fastest way to get out of trouble is to reboot forced or other if you can.Maverick then works fine as ever.Just embarrassing I have to undergo all this. Can this bug be solved in the near future? My PC is Intel 32 bits 2 core with 2 GHz and 320 GB and I have 4GB RAM but I think it has nothing to do with the hardware, it has more to do with the OS!

I noticed that every time I reboot some system settings sort of roll-back automatically to some time in the past.
So far I noticed these:
-All the aMule setting. Includes connection ports and Incoming folder, very annoying.
-Firefox search box engines. every reboot the list of engines rolls back to include a lot of engines i don't want and have to remove every time. this is the only thing in Firefox that is affected, bookmarks and add-ons stick.
-Keyboard layouts. Tried clicking "apply system-wide". still rolls-back after reboot.
What could cause this? How can I set these things permanently?
I'm using ubuntu 9.10 32-bit

As the title suggests, I have to restart alsa everytime I restart the computer. Obviously that's pretty annoying.
So once restart I normally do:
Code:
sudo alsa force-restart
It will then give me a few warnings (see screenshot 2) and then unload and reload all the drivers and everything works fine.

I have recently upgraded to the 10.04 Alpha and have been unable to reboot or shutdown. I know it's just an alpha and therefore problems are bound to exist, so I tried reinstalling from a live cd of Alpha 3. But I am still unable to reboot or shutdown.To clarify what happens, I click on shutdown or reboot, the pop-up appears, I click on the shutdown/reboot button and it seems to complete it. It says that processes have been killed and something has exited with 255. But my computer is still on. I am guessing that Ubuntu is shutting down, it's just not actually shutting my computer down or restarting it.

I am using Ubuntu Intrepid now, (no more Karmic, at least for some time)...
I connect to Internet through a proxy server. I have to configure my connection by going to Network Manager and then editing IPv4 settings, making the address selection manual instead of DHCP and then enter the static IP provided to me by the server and also the address of my gateway... Then I have to go to the Network Proxy under System --> Preferences and set my system proxy (Apply System Wide)...
Well that seems normal, except that I have to do the connection configuration part every time I reboot... Every time i reboot, the connection is back to default i.e.
Quote:
Name: Auto eth0
IPv4 Settings --> Method: Automatic(DHCP)
I have to change it again to
Quote:
Name: IST-LAN
IPv4 Settings --> Method: Manual
IP Address: 192.168.xxx.xxx
Netmask: 255.255.255.0
Gateway: 192.168.xxx.xxx
One of my friends reported the same thing to me after a fresh installation... So maybe that is a bug in the Network Manager of Interpid... I need to know a workaround, or a repair.

I did a bunch of stuff I read about here: [URL]
Okay, I don't think any of that would have hurt anything. Well then I was messing around and I created a shutdown launcher using the command
Code:
sudo shutdown -h now
I engaged the launcher to see what it would do and it caused a rather violent shutdown. When I turned my computer back on my emerald theme was gone and I can't seem to get it going again.

I installed Kubuntu on my Toshiba A135 with no problems at all...everything works: sound, wifi, LAN, etc...BUT whenever I reboot/restart the computer my Display and Audio settings revert back to default, and it doesn't happen when I log out, just when I restart/shutdown the computer. I have an Intel 945GM chipset and I have set my external Acer 23" monitor as the default and only monitor with a resolution of 1920x1080@60Hz using KDE's System Settings...And I chose to disable the laptop's internal monitor...but whenever I restart, the display returns to a 1024x800 cloned resolution (the default one)...which by the way looks hideous on a 23" monitor. And also the sound mixer goes back to the default levels.
So, can anyone help me out? I've been using Ubuntu for over 3 years and I've never had any problems like this one. I have just fell in love with Kubuntu, it looks and runs great, but this problem/bug is keeping me from being comfortable with it... I've been reading some things about XRandr and some commands and stuff and nothing have worked until now. I wonder, is it a common bug in Kubuntu or maybe an erroneous setting in the session manager....?

I would like to know if I can reboot my headless ubuntu machine from command line to a different OS on the same disk. To clarify, I want to do this without having to manually choose in GRUB.
OS1: Ubuntu on sda1- it is the default OS in an always on server.
OS2: Fedora on sda2 - have to login into this once in a while.
There are no monitors attached with the machine. So I cannot manually scroll through grub and choose Fedora. I want to know if there is a command I can issue remotely to the Ubuntu server to reboot to Fedora.

First Ubuntu install, everything is great except one small problem burning. Using Brasero
I burn CD fine Eject disc Drive is not accessible for reading or writing CD's until I reboot the computer Right click on the drive to mount volume and get "Unable to mount volume, no media in drive"
After reboot all is fine. I have tried multiple burners, same issue. USB burners can be unplugged, replugged in and used without a reboot.
Drive is a ASUS DRW 1612DL IDE
Happens in both Brasero and K3B
