Ubuntu Installation :: Installing 10.04 Beta 2 \ Way To Increase The Space Allocation To Root?

Apr 15, 2010

Tried installing using update-manager -d and received notification that my root does not have adequate space. Removed most of what I can and I am still short 560 mb or so. Even risking the removal of some questionable items I just don't see freeing up this much space to make it happen.Is there another way to install 10.04?Is there a way to increase the space allocation to root?Stupid question but, can I delete the image file for 2.6.31-20 without affecting the 2.6.31-20 version? Even if I can still not large enough to get to the 560 mb.

Fedora :: Went From FC13 To FC14 Now Gaming Graphics Shotty?

Jan 9, 2011

I had been running Fedora core 13. Everything was running fine. Gaming graphics were excellent. 3d acceleration was as well. Did a fresh install of fedora core 14 and now gaming graphics just plain suck. Colours are distorted, textures are shotty, lots of black spots in the distance.I've install mesa experimental drivers with no improvement. also messed with the settings in either game with little to no improvement

Specific games this is happening on are urban terror and nexuiz.Graphics card is Radeon HD 4650

# glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Mesa DRI R600 (RV730 9498) 20090101 TCL DRI2

General :: Memory Allocation - How To Disable Overcommit

Oct 17, 2010

I've been looking into memory overcommitting in Linux using /proc/sys/vm/overcommit_memory, and I've read a few articles which don't say the same thing. This doc, under the heading "Going in the wrong direction", goes on to say, "values 1: do overcommit, and 0 (default): don't", but then in the next few lines, it mentions, amongst similar things, that this isn't actually true and that 0 means "guess about how much overcommitment is reasonable". That means that memory overcommit isn't disabled using value 0, right?

It also says that 1 indicates "never refuse any malloc()", with 2 meaning "be precise about the overcommit - never commit a virtual address space larger than swap space plus a fraction overcommit_ratio of the physical memory." The Red Hat magazine, on the other hand states, "if the value is 0, then the kernel checks to determine if there is enough memory free to grant a memory request to a malloc call from an application. If there is enough memory, then the request is granted. Otherwise, it is denied and an error code is returned to the application."

This sounds exactly like disabling overcommit. "If the value is set to 1, then the kernel grants allocations above the amount of physical RAM and swap in the system as defined by the overcommit_ratio value.... If the setting in this file is 2, the kernel allows all memory allocations, regardless of the current memory allocation state." In terms of values 1 and 2, that is the opposite of what the previous doc said, right? What is actually correct, and if it is possible to 'disable' overcommit?

Programming :: Explorations In Memory Allocation In ANSI C?

Feb 8, 2011

I'm performing some explorations in terms of memory allocations in ANSI C, using the following compiler:

gcc version 4.1.2 20080704 (Red Hat 4.1.2-46)

and I started to try to make the compiler complain for a huge data structure, so I coded this:


I mean, I can always read the man entry for gcc but I rather ask because I can then have interaction...

Fedora Servers :: Virtual Machine Manager Won't Allow Memory Allocation Over 1024

Jan 26, 2010

I'm running Fedora 11 ( 8 GB memory on a AMD Phenom(tm) II X4 965 Processor, 4 core server I just built.The problem I have run into is any virtual machine that has >1024 MB memory assigned to it will not boot. As along as it has 1024 MB or less it boots fine.The symptom you see is a very quick message "Booting from hard disk" the screen then goes blank, you can't login through SSH, and can't ping the network address so I know it's not some crazy video problem hiding the boot process.The attachment are messages from a failed boot attempt.

Fedora :: User Memory Allocation - Set A Maximum Limit On The Amount Of Ram A User Can Utilize?

Jul 24, 2009

I have a few multi-user servers in an academic laboratory. I am having a problem with some users maxing out the available RAM, causing such sever slowdowns the machine essentially crashes. My servers are Dell Power Edge's running Ubuntu 8.10 Server Edition (Not my choice). I would like to set a maximum limit on the amount of ram a user can utilize. This morning I experimented with setting limits via /etc/security/limits.conf and using ulimit. Neither of them prevented my test program, a simple infinite loop of mallocs, from crashing the server.

Ubuntu :: Increase Maximum Amount Of Allowed Shared Memory?

May 17, 2011

My problem is I installed Zone Minder for camera security and I'm testing it on my laptop with the built in webcam and everything seems to work perfectly except when I try to view the live feed from the camera, it's just a black box. No video.

I checked this website and it's exactly the problem I'm having with a fix for it but his fix doesn't work. He says to type:

user@ubuntu:~$ sudo echo "256000000" > /proc/sys/kernel/shmmax
user@ubuntu:~$ sudo service apache2 restart
user@ubuntu:~$ sudo service zoneminder restart

But when I do the first line, I get this:

deemar@Clementine:~$ sudo echo "256000000" > /proc/sys/kernel/shmmax
bash: /proc/sys/kernel/shmmax: Permission denied

Ubuntu Installation :: Cannot Increase Monitor Resolution Onboard Graphics Card?

Nov 22, 2010

I know there are many threads on similar issues but I can't find anything that will work. Not sure if I need drivers or what to do - I feel really stupid as I should be able to get this right but I am at a brick wall. Basically I have a 20inch monitor hooked up to the on-board graphics card and cannot get higher resolution than 900 x 600. It should be at 1280 by 1240. This is a brand new install with the latest Ubuntu 10. Under monitor preferences its says 'unknown' for monitor type and I don't have any driver disk for this screen but never needed one previously.

Jan 22, 2011

Just installed Linux (Ubuntu 10.10-net book-i386) on an acer 5310 laptop, everything is working great except for the internet. Google home page takes over a minute to load on Firefox, the actual search results takes only a second but then it takes 2 or 3 minutes to load any site i click on. I have broadband, only 1mb, but it worked perfect on the previous OS, also using Firefox.

Ubuntu :: Acpi Causes Graphics To Slow Down?

Jan 3, 2010

I have to use acpi=off because my PC is crushing/freezing during installation and 2 mins after boot up. Currently I'm using acpi=ht to enable second CPU.

The problem is that my Intel graphic card is slow and Xorg is taking a lot of CPU.
I'm also not able to enable compiz when disabling acpi. The biggest problem is the MythTV that is so slow in the menu area alone that I'm not watching any TV in it lately.

When I'm not, it's crushing, no CPU spikes, no strange behavior just crushing without any logs.

Ubuntu 8.10 was running well on the box.

Ubuntu :: Graphics Very Slow On Dell Optiplex GX240

Feb 21, 2011

I installed Ubuntu 10.10 32-bit on a Dell Optiplex GX240, it has an ATI Rage 128 Pro Ultra TF (from lspci output) and all the graphics run very slow (I'm assuming because OpenGL and hardware acceleration are disabled). I Googled the issue and found several solutions but non of them worked. I tried installing the ATI Catalyst driver but it doesn't recognize the graphics card. I also tried to install the fglrx drivers but when I run fglrxinfo I get a segmentation fault. So the X server is running with the open source (r128) drivers and it's really slow.

OpenSUSE :: 11.3 - OpenOffice Slow Performance (Need More Memory)

Oct 1, 2010

Ever since 11.3 Open Office was performing "badly" to say the least. It loaded slow, with a few documents open "save-as" and selecting a different folder took up to a minute and so on. Anyway I had the suspicion that there maybe not enough memory allocated. Nothing within the OO settings worked.

Then I looked into yast=>/etc/sysconfig=>System=>Limits...
found "HARDLOCKLIMIT" set to "@256"
changed to "@512"......OK finished.

Ran a test with 10 documents open
a) Startup was much faster
b) Saveas instantly
c) PDF instantly
d) Selecting new folder instantly
Preliminary conclusion : Java(sun) and OO needs more memory

OpenSUSE Hardware :: 11.2 - Very Slow Graphics After Update

Jun 23, 2010

I just manually updated my opensuse 11.2 installation. This update included the xorg-x11-driver-video-radeonhd driver from version 1.3.0_20091026 to 1.3.0_20100216. As a result now all graphics operations are very slow, eg. redrawing a large window takes around 1sec when moving it to another position. With the old driver is was very smooth. Vlc previously worked very well, now it is not possible to watch a video even with a low resolution. I use a Radeon HD 3200 GFX chip which is on the motherboard (Asus) and additionally I have a separate GFX card (Radeon 3870) in the PCI-E slot which I don't use on Linux - just for gaming on Windows.

Red Hat :: Graphics Very Slow With CentOS 5 On Dell Laptop

Apr 28, 2010

I am using CentOS 5, I have recently installed it on my Dell LATITUDE laptop but the resolution was 800x600. I've tried to put it on 1680x1050 and it worked out well I guess but the graphics had become very slow. For example I have to wait 5 to 6 seconds to scroll from page to page in a pdf file. Minimizing a window takes also a lot of time. I have a NVIDIA card in my PC.

Fedora :: Firefox Becomes Unusably Slow / Uses Excessive Memory

Nov 23, 2010

I'm using Firefox 3.6.12 on Fedora 14 (64 bit) and have noticed that after using it for a while (and/or leaving the browser open for hours at a time), it becomes almost unusably slow and uses an excessive amount of memory. For example, any of the following can cause Firefox to temporarily (for 5 to 10 seconds or so) stop responding:

- clicking on a link
- opening or closing a tab
- scrolling
It will always start responding again, sometimes after the window darkens (to indicate that it's not responding) but it's so bad that it can't really be used. Closing it and opening it (restoring the tabs) again fixes it for a while, but the problem recurs. Regarding the memory usage, it was using 850MB (according to System Monitor) when I closed it, and having re-opened it and restored the tabs, it's now using under 200MB (but appears to be rising).

Another way that this manifests itself is that when trying to watch a Flash video (like iPlayer), it pauses for a second every 30 seconds or so, making it very annoying to watch them (I've switched to Chrome for this now, and am tempted to switch for general browsing, but like the plugins in Firefox).Is anyone else having these issues, and does anyone have any suggestions on how to fix it?

Slackware :: Slow Graphics With 13.37 And Radeon Mobility X1600

May 4, 2011

I've upgraded (reinstalled) from Slackware 13.1 to 13.37 on an old iMac and have problems with slow graphics.
lspci says this about the graphics card:


With Slackware 13.1 I had no KMS enabled and graphics speed was okay. It wasn't very good, but okay for everyday work. Now with 13.37 it's extremely slow. glxgears runs with only around 38 fps, no matter what I do. And every now and then when logging off, I get a black screen and no new kdm-login. But I can ssh into that machine and restart X by issuing 'init 3;init 4'.

KMS is enabled (I've also tried disabling it, but then KDE crashes right after logging in) and it's a fresh installation of 13.37 with a kernel.

What can I do?

I have to admin I don't know this video and X stuff very well and I used to have machines with NVIDIA cards.

If there's anything else than the usual Xorg.0.log needed.

To me the log doesn't look like there's any problem whatsoever:
