I have a HP laptop with an AMD Athlon X2 Dual Core QL-65 and an ATI Radeon card running Ubuntu 10.10 When I run a video file using Movie Player (or VLC) through the HDMI output to my TV the 'System Monitor' indicates that both processors are running at around 100% with the fan running continuously.

I have checked /proc/cpuinfo but i dont find any core details inside it and I can find only no of processor and its speed.
I have a VM setup in VirtualBox of Win XP. This VM has been setup for well over 4 years.
All of a sudden today, the VM started running very slow. I checked the task manager in Windows, nothing eating up PCU or memory there. I then ran htop. Attached is what I saw. There are many repeat processes with different PIDs.
Is this normal?
Edit: I have a Sony Vaio FJ170 laptop with Phoenix BIOS version R0060X6 & a broken DVD Drive. The BIOS doesn't support booting from USB (it does have 'External Drive Boot' option, but my USB stick doesn't get listed under boot devices in BIOS when connected to the laptop).
A few days ago I upgraded to Windows7, then installed Lucid through WUBI. With the help of another thread of mine (here), I changed the default boot option & timeout of Windows to zero to directly boot into Ubuntu. So far it was good. But recently I tried to get back to Windows for some reason but could not succeed as the F8 key no longer brings up the Window's Advance Boot Menu.
Is there another way to restore the dual boot menu timeout to get back to the Windows installation. Or even better, is there some way to make a fresh install of Windows & Ubuntu side-by-side without DVD drive. I am only 14 and absolutely new to Linux. The network booting methods given on the Internet were too complex for me to understand. I like Ubuntu but also need Windows for programming C++ & Photoshop CS4.
Currently I have a perfect setup of 3 monitors,2 GPUs running under Xinerama. I cannot get desktop effects running at Normal or Extra, when I try to enable either one I get the following message "The Composite extension is not available". Without Xinerama it works along with Compiz. I am running Ubuntu 9.04 x64 with a ATI HD4870 and ATI HD4350 GPU. I have the latest ATI display drivers (set up properly to my knowledge). Here is my xorg.conf file.

I'm trying to start an Oracle Integration server as user "oracle" at system startup and my approach was to place a couple of lines in /etc/rc.localsu oracle/home/oracle/startallSomething is not quite right about this as it seems to leave some processes owned by root.

The problem is that when running F11 (or even Ubuntu), my system shut off suddenly(not a normal OS shut down, but a sudden power off without any warning). This could have been a hardware trouble(heating) but it doesn't happen with Vista.
Machine specifications:
Maker: Toshiba
Model: Satellite L305D-S5881
AMD Turion X2 Dual Core Mobile Processor RM-70

I don't want to open up my machine unnecessarily, if it isn't a hardware issue.
I am not sure how to verify the bit length of the machine and the OS and does it create a compatibility issue ?
Your advise would be highly appreciated.

JIt was easy to check in Windows, but I just wanted to know if there's a way to check if Ubuntu is utilizing both cores of my processor (Pentium Core 2 Duo).
View 9 Replies View RelatedI am attempting to Run Ubuntu 10.10 on a system with 128 CPU cores (64 dual core processors), but Ubuntu is only detecting 32 cores. I've looked and looked and cannot find any information on this topic; is there a core limitation in the kernel configuration that I missed? Currently I am using Ubuntu 10.10 Desktop, would I have more luck with 10.10 Server or another version?
View 9 Replies View RelatedThere was windows 7 Home Basic pre installed onto Hcl Desktop at my Office, then I installed ubuntu 10.04 to it, everything was ok untill I restarted. When I select windows 7 from dual boot, it takes me back to dual boot grub page. So I did inserted Windows 7 cd and restored windows by this
Code:
bootrec.exe /fixboot
Now only windows 7 is working and booting. I want ubuntu 10.04 on the dual boot, how and what is exact method of recovering ubuntu without harming windows 7? Is it with ubuntu 10/04 cd?? If i do live cd and restore grub, will windows 7 work?? I haven't given any details of hd0 and root, i'll manage, just tell the procedure.
I have a notebook with AMD Athlon 64 QL-62 2 cores CPU. Normally the temperature is 50-52 Celsius in idle but with Ubuntu 10.04 beta 2 idle temp is 60 Celsius. /proc/cpuinfo shows both cores on 1GHz which is good but still temp is higher than usual. I tried to find solution using Google but I didn't find anything.

When I try to boot into Ubuntu though, it took me 17 minutes to get to a workable desktop. And once I was there it takes about 3 minutes to open an application like OpenOffice. Everything runs at decent speeds once it is open but that is still ridiculously slow speeds. I was expecting the 15 second boot times that I had heard about.

View 1 Replies View RelatedWas running dual boot 10.10 and winxp on a MSI P4M900 motherboard. Have two HDs - one with OSs and some storage and the other purely backup for storage and Ubuntu home. Motherboard died and going to be replaced by Gigabyte G31 board. I will be using the same video, audio PCI cards and memory from old board. Should I look to a clean install of 10.10 and then bring back to life from my backup files (bookmarks, email etc) or could I plug in hard drives and boot normally? There is conflicting advice when I google - some say its OK just to boot, the kernel will sort out the new mboard drivers, others say you need a clean install.
View 2 Replies View RelatedI have a desktop Windows PC with three hard drives. Having successfully installed Ubuntu on a laptop I used the same CD image to boot Ubuntu on my desktop machine. All seemed well so I selected the option to install alongside the existing OS. I left the choice of drive as presented by the installer (it was the largest one) and asked for an 80G partition for Ubuntu. The installation went well but when the machine was restarted it just booted straight into Windows. No sign of the bootloader menu. I'm guessing the BIOS doesn't look at the drive where Ubuntu is installed, and the installer did not put the bootloader on the Windows boot drive. The Windows drive is too small to install Ubuntu there.How do I fix this so that I can dual boot, or alternatively how do I get rid of Ubuntu and reclaim the 80G for Windows?

I am running Natty on a Dell Inspiron 6000 under dual boot. Now Ubuntu refuses to load. GRUB goes along to a point where the final message in both regular and recovery modes is 81.8921591 atal: SRST failed (errno=-16). Is there any way I can recover short of having a professional rescue my data from the hard disk and totally redoing the install. I have had this problem in previous versions but never fatally before. My computer works fine under Windows.

Programs greyout and become completely unresponsive for long periods of time and cpu usage on one or both cores ramps up. As I type it is c.80% on both. System Monitor shows usage on the cores mirroring one another. top in terminal shows Xorg at 99%. I have attached a screenshot. I have rolled back and/or reloaded the Nvidia graphics drivers to no effect.
View 9 Replies View RelatedThis is a recollection of my experience using Microsoft Surface Pro 3. I am running Debian Jessie RC1, using the latest linux kernel (as of now, 3.19).
Assume that everything works, except:
- grub2 does not allow to select menu entries without TypeCover/USB Keyboard (Ubuntu had a popup software keyboard in the live CD)
- there is no "right button click" on the touchscreen. Most interfaces use a long press as a right click.
- the touchscreen is sometimes unresponsive, especially when plugging/unplugging the TypeCover;
- cameras don't work (although there is a fix)
- wireless card works 80% of the time only (but the newest marvell firmware from github solves the problem)
- secure boot does not work (need to disable that from the boot menu)
- touchpad gestures don't work (e.g. two fingers scrolling - this is particularly puzzling, as Ubuntu 14.10 live had the touchpad working (including two fingers scrolling) but not the TypeCover)
- touchpad and touchscreen scrolling do not work in certain applications (e.g. in Iceweasel one needs to install an add-on)
- pen works (even when the touchscreen is unresponsive), but only one of three buttons work (with xournal)
I would like to use my second monitor with my Slackware (Laptop) setup but they are different sizes/resolutions.
This is no problem with KDE but before X is started and when X ends there are big issues with the TTY0 console being distorted.
Is it possible to disable the second monitor when X is not running?
(Slackware64Current, ATI Mobility Radeon HD3200 card)
I essentially want the second monitor to activate ONLY in the event of an X Session and turn off when X halts.
My previous OS was openSUSE 11.4 KDE. In system monitor I used to see frequency scaling of both cores . Know thats not a case. I have Dell Latitude D420, with Core Duo U2500 @ 1.20Ghz, using Debian testing (Wheezy) 32bit, GNOME. Please help! There is no purpose to use a system which drains max. half capacity of a machine. hOPE, that is not a case . How do I know if both cores are working?
View 6 Replies View RelatedWhen I was using Virtual Box in Windows 7, I could choose how many CPU cores to assign to the guest OS. Now I'm using Linux, and when I installed Virtual Box, I couldn't find that option. System Monitor shows that when the VM is busy only one CPU core goes to 100% while the rest are near 0%. How can I make Virtual Box in Linux use multiple CPU cores?

I am running RHEL 5.5 on a Sun 4450 with 24 cores. We use Sybase database. Licensing for Sybase is by core.

I have recently set up a dual boot comp running Windows 7 and Fedora 13 (test) and began noticing that after a short while,was taking forever to access web pages. When I look at my router which is running DD-WRT I noticed my active connections was over 500 whereas should only be around 200 maybe or less. This does not occur under windows,so am not sure where to begin.box is running 64 bit quad core processor.
