Enabling PAE to Support More-than 3GB of RAM
I was wondering why ubuntu 32bit was having access to only 3gb of RAM even if we have more than that. Did a bit of googling on this and found the following..
Can ubuntu 32bit support morethan 3gb ram?
Yes. It Can with a special kernel like:
or
How to install this kernel?
just type the following to install it

What is the RISK? Little Performance degradation. Issues with proprietary software drivers. (Like nVidia..etc) Processor and H/W must support PAE.
For those without any proprietary drivers can make this happen easily with the above commands to install the new kernel.
I need help form you guys to install even if someone has a proprietary driver such as nVidia. I probably think one should reinstall the nvidia driver. I need help on this part of the issue.
I want to know how to get the details of all files in my system more than 20mb or some specific amount of file size in Ubuntu terminal by using commands.
I have a HP laptop which can support 1600x900. But after I install ubuntu 9.10 on it, it can only support up to 1280x700. My laptop has a Nvidia graphics card. And i am using GNOME as my desktop environment.
I'm trying to find out when QME2572 (Qlogic) card became support by the kernel. We have a RHEL 5.1 system that is moving to new hardware, however the kernel at this release doesn't support the new hardware, due to the Qlogic card change. I tired the Redhat KB and Bugzilla. Is there a Kernel change list etc I can search. Never really played around with the kernel too much so I'm just after some pointers for looking up this information. Offically its not supported until Redhat 5.3, I'm trying trying to research kernel info so I can tell the customer they have to upgrade.
I'm looking to dual-boot Windows 7 and Debian 6 upon its release on my sister's laptop. I want to share a partition between the two of them so that /home points to this directory and the Windows equivalent also points to it (C:Users).
Anyway, I've heard good and bad things about the NTFSMount driver (I think it's NTFS-3G now) and the NTFSprogs project and so I am not so certain what I should believe. I do know that NTFS has relatively high overhead, though I do not recall the source of this assertion, so I am considering the use of EXFAT. An open source EXFAT project is hosted on Google Code at [url] and it utilizes the kernel module FUSE.
I'm quite certain that I've got everything covered on the Windows side -- that is, I know that both NTFS and EXFAT will be suitable filesystems for my required usage.
My issue is that I'm curious which will have superior performance and stability in Debian. I planned on building the package from source and mounting the device in my FSTAB but I have also found a PPA for Ubuntu on Launchpad at [url] that I could borrow the debian/rules from and make a .deb package from.
What do you guys think? Should I go at it with the EXFAT or NTFS partitioning? Is NTFS-3G actually fairly supported at this point? Or perhaps should I consider some alternate method?
I have also considered that the only files she will be sharing are those of music, videos, and pictures so it could be better to just link /home/xxxx/Pictures (Music and Videos, too) to the new partition instead of all of /home.
I have a n2pap-lite motherboard with a AMD Sempron 2800+. My host clock is at 133mhz when it needs to at least be at 166mhz to be a AMD Sempron 2800+... I installed the system on 100mhz clock not thinking that it mattered.
It says on guides that it will ask me to reboot but it doesn't, so I manually did it and put the CPU Frequency Monitor on my taskbar. It does not have the options like it shows in the screenshots to set my CPU frequency..
Ubuntu rocks but I am having trouble enabling PAE.
I want to do it to have my full 4Gb RAM recognized by my 32bit OS. At the moment System Monitor only recognizes 3.2Gb and the command "free -m" shows the same value.
I followed these instructions but they don't seem to work: [URL]
PS: The point is to really understand how to achieve this and not to start a debate "32bit vs 64bit OS choice"
After my previous stint with 10.10 I've gone back to 10.04 because it boots in 20 seconds instead of 70+ and 10.10 didn't really seem to offer much new stuff that I need. Except one thing. When 10.10 boots, it automatically connects to whatever wireless network is set to Auto. 10.04 however, doesn't. I have to right click the tray applet and click on "Enable Wireless" and only then does it connect to the Auto networks. After a reboot, it's forgotten that I've clicked on "Enable Wireless" and I have to do it all over again.
I've found this thread that seems to describe the same problem and the only working suggesting is to use wicd instead of network-manager.
Does anybody know of a way to make it work using network manager? Do you know what command clicking on "Enable Wireless" runs - if I could just run that in an init script, problem solved. I thought it would be; ifconfig wlan0 up but that doesn't seem to do anything at all (wlan0 is definitely the right adapter)
on my Linux Ubuntu 8.04 machine, I recently added a new user. When ever I use it, I can't get to System~Administration~Synaptic Package Manager, for the sole reason that it does not show up in the System~Administration list. Also, some other things don't show up, such as hardware drivers.
I'm using an ATI Radeon HD 6850, and although drivers aren't enabled, 11.04 fits my resolution, and has animation/shadows. I need to enable drivers so games like Minecraft will run better. Whenever I install the drivers, 11.04 fails to load, or it'll just give me a barrage of glitches. How can I install the latest ATI Drivers for Ubuntu 11.04?
I am having a problem using my laptop's special keys to toggle my touchpad on and off on my ASUS G73JH laptop, running Ubuntu 10.10 (2.6.35-28-generic-pae).
First, some preliminaries:
My touchpad works just fine, but it does not respond to my laptop's special key, Fn+F9.
In /etc/acpi/events I have the following script, "asus-touchpad":
Code: # /etc/acpi/events/asus-touchpad # This is called when the user presses the touchpad button and calls # /etc/acpi/asus-touchpad.sh for further processing.
due to a crash on window's part my computer crashed and I decided to install the latest version of Ubuntu. (9.10) However as it happened, it was actually incompatible with the usb on my computer an Acer AM5641 desktop. So I opted for 8.10 which works like a charm except for the fact that the restricted drivers for my graphics card (an Nvidia 7900 GS that I installed) don't work. After clicking "enable driver" everything appears to go as normal. Except for the fact that when I restart it, it automatically goes into safe mode, and i can't save it at a higher resolution than 800x600.
I could not find any way to enable dead keys on my keyboard on Lubuntu 10.04 via gui.I created xorg.conf by using X -configure command and tried to add followings into /etc/X11/xorg.conf but it did not work.
I have a frustrating problem - Apache will serve PHP pages correctly from /var/www but any PHP files in /home/username/public_html are not correctly processed and instead are sent to the browser as a download attempt (i.e. they are not passed to the PHP interpreter).
I have googled and followed the instructions about commenting out the lines in /etc/apache2/mods_enabled/php5.conf, which at present looks like this:
I been having this problem with the login screen after i enabled it. It shows a little window with the the ubuntu logo with my computer's name underneath with the login button. Clicking the button does nothing but when I hit enter it seems like its booting up but freezes after it says "checking battery [done]" or something like that. is it a problem with the login screen? If so how do I fix it? If not what is the problem?
Ubuntu works fine until I enable the visual effects to EXTRA. The computer then freezes, no mouse response, no keyboard response, have to hard restart.
After upgrading to natty alpha I enabled the nvida graphics drivers. Now I can't boot and get stuck on a purple screen, without grub. Can I with a live cd revert the drivers back to normal?
I've been having an issue for the last day or so. I have an HP Pavilion dv8000 running 10.10. Whenever I boot with the Wireless activated, it will lock about 3-4 seconds into the log-in screen (I'm guessing when it connects to my router). If I have the wireless deactivated (like now), I am able to use the ethernet connection, or (like now) use my phone to tether internet. But, as soon as I click the wireless to active, locks up. The wireless activity light flashes, but that's all.
I'm pretty good about updating whenever I use my laptop, but I think something in the most recent update may have broken my wireless connection.
I am trying the daily build of Ubuntu 11.04. When I try to enable Xinerama, so that I can move windows between my two displays, then I log out, and back in, it simply breaks Unity.
I was getting the sidebar, almost on the right side, and the screen was all broken, then the behaviour changed to simply not displaying anithing, Unity not loading whatsoever.
I turned off Xinerama (by editing my xorg.conf) and diabled it, and Unity works perfect.
I am using ubuntu 10.04 on lenovo g430, last night I switch off the device while it was connected to network and shut down the computer. But after that i switch on the device was disabled.I use to enable the device through Fn+F5 key which controls the device in windows but the keys does not work in ubuntu. I am using broadcom 802.11g device.
I tried out Xubuntu 10.10 on one of my older computers. Got it installed without a problem. Added the restricted driver module that I needed Nvidia, added the Compiz settings manager, but I cant seem to find a way to enable desktop effects. I realize that Xubuntu uses the XFCE window manger which is sort of light weight compared to Gnome or KDE, so I am asking if anyone has managed to get the desktop effects running in a similar environment. I checked and observed that the nvidia module has been loaded.
I need a textbrowser with Javascript Support. I have compiled the elinks stable 0.11x and the unstable 0.12x version mit JavaScript Support (js moz dev). Both browsers can be started and showed websites normaly. But no javascript, even simple tests like [URL] failed. I started elink with ./elink and typed then the url.
So I am trying to add some sites to my server, right now I have an active site at www2.site.tld. As a test, I copied [URL]to [URL], and changed only the line
ServerName www2.site.tld
to
ServerName what.site.tld
as well as renaming the lines for the log files appropriately then
which by everything I have read should result in what.site.tld being identical to www.site.tld. Instead, it flat-out does not resolve. Apache does create some blank log files in /var/www/
I've recently installed Xubuntu Lucid Beta2 on my new laptop. But I'm unable to turn the bell back on. The 'pcspkr'-module is removed from the blacklist and is loaded. However, 'alsamixer' doesn't show me any volume-options for the beep. However, 'echo -e "a"' still doesn't make a sound. I've installed the 'beep'-package, and it works, thus I am assuming that the hardware-bell itself does WORK fine. It's just deactivated/muted somewhere, and I can't find the option to turn it back on.
Everything works great at the moment, no hardware problems or anything like that. But whenever I enable the proprietary nVidia driver 185, it causes the boot screen to not come up, Ubuntu stops recognising my sound-card and refuses to work and when I try to shut down or restart, it just takes me back to the log in screen. When I remove the driver, everything works okay again.
enabling parallel compilation of kernel source.I've read that setting the CONCURRENCY_LEVEL environment variable should do that. The problem is that I see only one instance of a running gcc in top, notwithstanding I have set "export CONCURRENCY_LEVEL=5".
How do I do that ? Currently I have Kubuntu/Mint KDE installed as my main and only OS so the GRUB splash is disabled by default, how do I enable that (so I'm able to change the boot commands to go to single user mode).?
