I just wanted to glean some sort of a general average and compare my system with everyones. post your computers:boot time of course hardware specifications (processor, HDD, RAM, etc.) distribution if it's a laptop or desktop (or a netbook ) Mine is 43 seconds, running Ubuntu 9.10 on a netbook. My hardware specs: Intel Atom 1.6 GHz 320 GB 7200 rpm HDD 2 GB RAM
View 14 Repliesmy desktop pc is acting very strange. cold boots often take up to 10 attempts before the computer successfully boots. after the 1st successful boot, i can expect 1-3 "glitches". here's what happens:
the first few cold boots fail at various points during the boot process. there appears to be no pattern to it. when it happens, the machine is completely locked up. it responds to nothing, except holding in the power switch for 5 seconds. i'll go through this procedure several times.
finally, it will boot all the way to a desktop. from there, once i log it, i can expect it to lock up completely, usually once or twice. and then, finally, the screen will go blank and it will suddenly be back at the login screen.
usually, once i log in that last time, it's at least usable, although hardly stable. watching flash video seems to cause a complete lockup, with the sound looping. it doesn't matter where the content is coming from (videos or similar) nor does it matter which browser i'm using (firefox or chrome). i've stopped visiting videos-type sites in the meantime.
this installation has always been a tad bit screwy. 99% of the time, firefox fails to shut down properly, resulting in a message letting me know that a crash was detected. earlier today, i was alerted to 3 kernel crashes simultaneously.
right now, i'm using the pc, as normal. the random nature of the problems would lead me to believe it was hardware-related, specifically something like memory (ram). however, i installed memtest86+ and ran it. i walked away for 4+ hours. came back, it was running, no errors were found. i stopped the test and booted, trouble-free.
the pc seems to be stable enough for a backup, but this does have me concerned...obviously. i'm debating wiping the drive clean and installing f13, just as a test. if it's screwy as well, it would have to be hardware-related, wouldn't you think??
how do you measure performance on a computer?I know there are benchmark sites, they do give a general guidance in selection. However, I want to learn how to build a cluster from commodity parts and want to make sure it is equivalent to a specific server in performance.I know clustering is a bit abstract and it will be difficult to measure direct performance and compare it to one specific board. I am fine with that
View 5 Replies View RelatedWith windows I was able to leave my computer on my lap and go for hours on end its never overheated on me and it still doesn't with windows, but with ubuntu it will last around 30-1h then it will overheat or even faster if I do anything like play a game or watch flash. And its not a problem with the new flash release because last year when I had ubuntu 10.04 it did the same thing (im on 10.10)

View 5 Replies View RelatedI recently upgraded to 11.04, and after messing around with Unity for awhile decided I'd try out Gnome 3.After rebooting to finish the installation, I noticed that the interface had reverted to what my desktop looked like in 10.10, except the color scheme was different. I also got an error message saying my computer's graphics couldn't handle Gnome 3 (I'm on a netbook). Then I went online to look up instructions on how to switch back to Unity (since the option wasn't available on the login screen). After following the first step, which involved entering a command into the terminal, I left the house for awhile.
When I got back, the screen was black with white text (terminal-esque) asking for my username. After typing it in and pressing enter, it asked for my password, and after entering that it became a "terminal". This screen comes up every time I start my computer now, and I have no idea what to do. I could reinstall Ubuntu from a flash drive, but I want to be able to access my files. Is there any way to get around this, or recover my files without taking out the hard drive? As you can probably tell from my post, I'm very new to Ubuntu and Linux, and the mess I'm now in is the result of acting on uneducated impulse.
My computer starts up and, usually, gets to a desktop (I can login). If I click on a folder to open it, the computer just dies. No power at all. Sometimes it doesnt even make it through the boot up stage, just stopping before getting to grub. This happens in F10 and F13, whether the grub is on the harddrive or a USB key. I'm thinking that I might need a new power supply, but I'm also wondering if I might have fried the CPU, which ran for several days at 50 or so degrees, (for sensor one on the little gnome panel applet). But it did go over 60 a couple of times and die from overheating. These higher temperatures were achieved by running CPU intense software, with the cores in use running at 100% each. The higher temperatures were from running it with all four cores.

View 3 Replies View RelatedI have tried to keep away from posting this seeing how many have had the same problem but this is getting to the point of me just selling my computer out of shear frustration. Ive got Windows XP and Ubuntu 10.04lts. For a while they all ran fine together till my Windows drive gave out and ever since I tried to remove the drive GRUB recovery has been popping up. I even tried to put the drive back in and the computer still wont boot anything. Ive got 4 different live boots and neither one works, Ive tried to boot with my internal dvd drive and a usb one, there is always a Grub error. When I put in the ls command and find my only non"unknown filesystem" it still says "bad filename". I guess where im getting at is grub wont even let me reformat my computer or boot from anything without saying "no such device: 32d98-e0b3-451b-809b-ae6562ccb701"

View 9 Replies View RelatedMy laptop will be fine, then it turns off then immediately boots itself to a blank screen and no hard drive activity. This has happened 3 times today and never before. what ive done so far The first time this happened i tried turning it off and back on, still no screen and no hard drive activity so i took one of the RAM sticks out. Booted fine... To confirm that the RAM was bad i put it back and tried booting again, unfortunately it booted fine... i thought it was a fluke.
Until his happened a second time and instead of taking the RAM out, i waited a half hour and rebooted and it started booting fine, i turned my back for a sec and it was dead again. I have taken that RAM module out and am hoping it will not happen again, but it could well be the other RAM module since i really don't know or even if it is RAM at all.
Question is. Is this a RAM issue or something else? Where can i find a log to see what happened immediately prior to it offing itself? What's the chances it's the heatsync? (the laptop doesn't feel as hot as it sometimes does)
I would like to be able to auto login to my centOS 5.4 linux machine when it boots up. Is there a intuitive way to do this? I'm running the motif window manager. The problem is that my computer boots up into motif but it asks me to login as root. I would like to eliminate this.

Like half of my wireless just the mail icon from the indicator applet half the trash can or show desktop or just the power button from the indicator applet session. After I log out and log back in either once or twice that usually fixes it. I am using Ubuntu 10.04 with gnome 2.30.2.

Setting 1152Xwhatever resolution failed. Setting to 1024X768. My xorg.conf.old file is completely empty, so I have no idea what the original settings were. I have tried removing and reinstalling xserver.xorg but that hasn't seemed to get me anywhere. I have also used the "apt-cache search nvidia" command to see what drivers could be installed, but every single driver that I attempt to remove isn't installed.
