Ubuntu :: Significance Of Swap Partition - Cpu Light Keeps Blinking Continuously And The Mouse Movement Is Very Slow

Aug 2, 2010

I need to know the necessity of swap partition in Ubuntu.. I have recently bought a new HD and installed Ubuntu(with NO swap,only Ubuntu on a single partition) on it and am facing frequent,random hanging issues with it.. Earlier,my old HD used an swap partition along with main partition and i never faced hanging issues at that time..

Actually, when in hanging mode,the cpu light keeps blinking continuously and the mouse movement is very slow,the screen also becomes dim.After sometime,it comes out of hanging mode and mouse movement becomes normal.Sometimes,even after waiting for 15-20 minutes,it does not come out of hanging mode and the system has to be restarted.(this is what forced me to look for a possible solution to this)

Ubuntu / Apple :: 10.04 - Mouse Movement And Zigzagging?

Jun 21, 2010

Anyway, just installed 10.04 desktop on a 4,1 Macbook. I've pretty much got everything to where I like it. My only real problem is the track pad/mouse not working right. Unless I move the the mouse perfectly vertical/horizontal the mouse starts zigzagging like crazy. The slower I move the mouse the more prominent the problem seems to be. I've tried playing with the mouse settings under preferences but nothing got it working smoothly.

Ubuntu :: Possible To Get Quality Mouse Movement Like In Win7?

Jan 19, 2011

I've been using Windows (7) a little, and I just noticed that the mouse movement is simply infinite times better than Ubuntu's. On Windows I was able to actually "draw" things using the mouse, and it's amazingly comfortable. You actually feel on control of it. On Ubuntu I've tried to reduce the mouse polling rate to 2ms, and a number of different speed and acceleration combinations, but It seems impossible to achieve the same quality (or at least something acceptable after trying Windows).

Now that I'm used to Windows' mouse movement, I feel extremely uncomfortable and have difficult even to target links on webpages. Is there a way to increase the movement quality? My mouse is a Microsoft Basic Mouse. I'm attaching a file of a circle drawn with mouse on Windows and an attempt to reproduce it on Ubuntu.

General :: Ubuntu 10.10 Freezes With Caps Light Blinking

Mar 4, 2011

i have been using it since a friend suggested to use it a month or so ago. I have knowledge of computers so I am not ignorant of everything (I say this for the linux pros in case this is a simple solution, and I have checked many forums before actually posting this question with no luck) and have tried several options. My laptop freezes at random times with the caps lock light blinking which seems a little strange. the only correlation I can make to this problem is that every time I use only wifi without the ethernet cable plugged in it will freeze. I have read a few forums that say it could be a bug in the wireless card drivers and some suggest it could also be graphic card drivers but it seems to only happen when wifi is enabled.I am using an ASUS G73 series with an ATI Mobility Radeon HD 5870 1GB GDDR5 graphics card, 8GB DDR3-1066 RAM, Atheros AR9285 802.11n Wireless LAN adapter, and an Intel Core i7-720QM processor (1.6GHz/2.8GHz Turbo Mode, 6MB L3 cache). I am also running Ubuntu 10.10 off of a 320 GB seagate Momentus and windows 7 off the stock 500 GB Seagate Momentus.

Fedora Networking :: Blinking Wifi Light During Network Activity F15 / Fix It?

Jul 1, 2011

I had a problem with the new network manager a week ago and got it solved with help from the forum so now I'm back again. I have a dual boot with Windows 7 (I have to use it when serving my corporate masters) so I wasn't in my Fedora partition much this week.
I just noticed this and I'm positive it wasn't doing it before my network manager problem but I'm not sure when it started or if they're related.
I'm running F15. The machine is an HP Elitebook 8440p and has a wifi light that is also a touch button to turn the wireless on/off. Whenever there is activity on the network now it blinks between orange and blue. I know that isn't really a big deal but it's really annoying and is driving me completely nuts!! The normal behavior is orange when it's off, solid blue when it's on (or connected) and blinks orange/blue just while it's connecting. During network activity it's always been just solid blue and that's what I want.
I found a script that some Ubuntu users said fixed the same problem but when I tried to copy it the directory they said to put it in "/etc/network/ifup.d" doesn't exist. I'm assuming that's a distro difference between Ubuntu and Fedora?
Has anyone else seen this? Any ideas how to fix it?

Ubuntu Installation :: Computer Randomly Freezes And Caps Lock Light Blinking

Feb 11, 2010

I installed Linux yesterday alongside windows vista. Everything went very smooth. I restarted the computer multiple times without issue, and the menu would pop up asking me which os to load. Everything was good. But today I attempted to boot up my computer and nothing happens. The screen just stay black. The lights come on on the laptop, but nothing else. Either I try to boot it and it goes on then off quickly, or it just sits there, still on, with a black screen. I don't know if this is related, but when I was messing around with ubuntu yesterday after I installed it, it would randomly freeze and my caps lock light kept blinking on and off. I was forced to restart when this happened and then everything would be ok.

Security :: Turned The Router Off And On Again A Few Minutes Later Initially The Light Was Still Blinking Abnormally?

Mar 31, 2010

Not doubt this sounds alarmist, and perhaps it is... anyway, earlier tonight my mum complained that her home network connection wasn't working. After complaining about Windows and running a virus scan, I returned to my laptop, only to find my Ubuntu 10.04 was having the same problem. Then I noticed the wireless connection light (next to send and receive, which always blinks anyway) was constantly flashing, as if transmitting data, even though neither of us was connected, of course. I turned the router off and on again a few minutes later. Initially the light was still blinking abnormally, but I could now access the internet, as could mum, so I ignored it.

Later on, while the virus scan on mum's computer was running, Windows notified her she was running out of hard drive space - normally about 30GB of the 51GB HD is used on her laptop, but suddenly 50GB had been used. I also noticed my 275GB Ubuntu partition had 235GB free (although total size of files on disk was 128TB - a bug perhaps?), i.e. 40GB used, which seems pretty large for a rather fresh install and a handful of documents!Currently, everything's normal where my router's concerned (no blinking lights except for my browsing), and my Lucid partition is still showing 235GB free (strangely, mum's laptop now shows 46GB used instead of 50GB). So, what do we make of all this? Were our computers hacked for storage space?

Ubuntu Networking :: Wireless Light Constantly Blinking On Compaq Presario CQ60 Laptop

May 13, 2010

I have a Compaq Presario CQ60 laptop and have one of those wireless light indicators. For me the light glows orange when the wireless is OFF and blue when the wireless is ON. In Ubuntu 9.10 (Karmic) the light was always orange, even if the Wireless was on, but my wireless worked right out of the box so I was grateful for that, but since upgrading to Ubuntu 10.04 (Lucid) I've noticed that my wireless light alternates between orange and blue frequently and sometimes flashes madly when wireless activity is occurring.

I was wondering if there is a fix for this as it can get quite annoying, the light sometimes stays blue for a while but will ultimately keep going back to orange and vice-versa, my friend who also has a Compaq Presario CQ61 (Revised model of mine) has his wireless light constantly blinking orange and blue no matter what.The wireless itself works fine, I can connect to any wireless connection and use it without having to install anything else, so it does work out of the box, which again, I'm grateful for.The wireless adapter is a Atheros AR5001 Wireless network adapter. Do I need to install additional packages or drivers to get the wireless adapter to work properly?

Ubuntu Installation :: Broken - After Failed Upgrade To 11.04 - Everything Just Hanged - No Mouse Movement - No Hard Disk Activities

May 9, 2011

I tried to upgrade my Ubuntu 10.10 to 11.04 on my netbook. I choose the option to upgrade on the Update Manager. All packages had been downloaded, and the installer was busy to replace all the old packages.

During the update I noticed that my internet stopped working, so I disabled my wifi, so it couldn't interupt the upgrade. After a half an hour, I found out my internet worked again, so I pressed the wifi-button again on my laptop, so the wifi would turn on, but after that move my screen hanged, and the upgrade wasn't done yet. I pressed the powerbutton for 5 seconds, because there was nothing else I could do.. Everything just hanged, no mouse movement, no hard disk activities, just a frozen screen.

After this problem I rebooted, and I already knew what I was going to see, Ubuntu couldn't be loaded anymore (and it still can't).

Is there anybody who can help me to restore my laptop? There are really important things for college on the harddisk in the /home/ folder, but I was too stupid to forget to make a backup.. I mostly make backups of everything you can think of, but I thought it won't be neccessary.. damn..

I know that you can restore files using a live-usb (no cd, because it's a netbook), but I choose during the installation the option to 'encrypt' my documents.. So is it still possible to restore my documents, photo's etc. from the home-folder? I really need to get those things back..

When I try to boot all I get on my screen is the text (in Dutch): 'Disk partition / is not ready or is not found - Keep waiting or press S to cancel mounting, or press M to recover manually' The manual recovery doesn't do anything at all, and by the way, booting in the 'recovery mode' won't work either.

Ubuntu :: Freeze After Login In 10.10 (no Mouse Movement And Only Login Bg Visible)?

Feb 15, 2011

I installed xorg-edgers around the time the issue started, but I install and uninstall packages so often its hard to tell if this was the cause. Regardless, I ppa-purged the xorg-edgers ppa, reinstalled the proprietary nvidia drivers, and created a new user account, to no avail. I also wiped the /tmp directory, and reinstalled compiz, and tried dpkg-reconfigure -phigh xserver-xorg.

So far nothing has worked; I've checked out dmesg and /var/log/syslog, and nothing seems to be amiss, but admittedly I'm not sure what exactly to look for. I have a feeling its an issue with X being broken now, regardless of my attempts to downgrade, but I don't know how to go about correcting it.

Hardware :: PC Wont Power-on - Power-light Blinking?

Oct 30, 2010

I had unplugged my PC last night as sometimes there's storms at night this morning I plugged in PC and the power light is blinking and the PC wont come on at all tried different power cord, same result

PC is a AMD athlon64 3300+ 2.4ghz SiS graphics

If it is the power supply, how do I find new one as I've never had to replace anything on it or any other PC?

Also, I really need access to the hard drive but it's a weird hard drive and was wondering if I could put that hard drive in my K7 PC, which already has 2 drives in it can a pc have 3 drives? do I have to add/have another ribbon cable for 3rd drive?

Ubuntu :: Slow Boot (Blinking Cursor) With 10.04 Upgrade

May 3, 2010

I am getting a much slower boot with the 10.04 upgrade. After choosing which partition to use I get the blinking white cursor in the upper left hand corner and the "Boot from (hd0,4) ext 3..." sits there for a while before coming to the log in screen. There have been quite a few posts about this, a lot of people are saying disabling the floppy drive in the BIOS has worked for them. I don't have a floppy drive on my laptop.

just upgraded to Lucid. When booting, I get a blinking cursor on a black screen for 30 sec. Then I get some flashes of text about UDEV. Finally, I get a desktop after about 30 more sec.

Any way to speed this up? I've already tried disabling my nonexistent floppy drive in the bios, but it didn't help.

Hardware :: Mouse Froze - OS Completely Unresponsive - PC's HD Led Was Fully On Without Blinking

Mar 18, 2011

I wanted to have a partition with Debian, but after lots of unsolved errors I went to the more compatible Ubuntu. To my demise, he suffered from errors too. Without counting on the numerous errors and bugs experienced with other linuxes and windows. Given my computer's history of failing, I'd like to know what's wrong with him, and I'll take the opportunity to see if I can make Ubuntu work allright, so I'll describe his last error.

Actually more like a first error. Right after the instalation process (Ubuntu 10.10), I ran apt-get upgrade, and went to Firefox to waste time. Soon after, everything but the mouse froze, OS completely unresponsive. One strange thing was that the PC's HD led was fully on, without blinking.

Stranger is that this also happened at Windows XP, but at the time, he wasn't accessing the HD, and it didn't froze, just got excruciatingly slow. And it stayed like that on every boot. At least I was able to do some tasks and install SliTaz on my pendrive so I could use the computer. But suddenly it came back to normal.

As I'm talking about windows, I'll add that he bluescreens seldomly, always refering to some winsomething.dll .

The HD is almost brand new.
The RAM is not too old.
The oldest in my computer is the mobo and the processor.
It's not overheating because the power supply's fan is not working, so the computer always run with a home fan in it.

Fedora :: Screen Goes Black - Mouse Frozen - Caps-lock Blinking

Dec 14, 2009

I keep starting up Fedora and I'm not able to get far (although it's not always at the same time) before my screen will go black, except it shows the mouse/cursor - but it's frozen, and thhen the caps-lock light starts blinking and I can't do anything or get it to recover. Sometimes it happens after 30 seconds, sometimes 40+ seconds and sometimes within 15 or so seconds.

How do I stop this and diagnose this?

I've tried, in the boot-startup to choose an older kernel version, butt the same thing occurs!

I have:
Fedora 11
Kernel: 2.6.29.6-217.2.16.fc11 i586
Asus EEE PC 1002HA

One other thing, it does always seem to happen after I've turned on wireless. And I've been using F11 for months now with no issue.

Ubuntu :: Delete Snow Leopard Partition - Format Swap Disk Partition To Something Else

Feb 23, 2011

I had a drive with a partition layout like so:

~50gig Windows 7 - NTFS
~100gig Ubuntu - EXT3
~100gig Snow Leopard - HFS+
~100gig Extended Partition
-- ~100gig Swap Disk - exFat

I wanted to delete the Snow Leopard partition and format the Swap Disk partition to something else. exFat was causing major file size bloat on small files. QT sdk bloated to like 11 gigs or something ridiculous like that. Anyways, I loaded up an Ubuntu 10.04 LTS live cd and gparted then deleted the Snow Leopard partition. Gparted said "Mission Accomplished" and tried to rescan the drive, but never found it. At this point I restarted the computer, a dell laptop, which didn't boot with an unable to find a bootable device error. The ubuntu live cd doesn't see the drive anymore. gparted scans for drives indefinitely and fdisk -l has no output.

Hardware :: Invalid Partition Table For Swap Partition That Moved With Gparted?

Feb 8, 2010

I was reading another thread about someone with a bad partition table and I decided to join this forum. I'm not going to take any drastic actions with the partition (/dev/sda3) in question. I am going to wait for instructions on what to do first. I am not very good with Linux and need some hand holding. System: DELL 4550 Dual-Booted with XP and Ubuntu. Works OK, just no swap. Well, here's what I did: I deleted a partition for Windows XP Pro because it was a trial, and it ran out. I then decided to slide the swap partition for the Ubuntu Linux that I dual-boot into over. (If this was successful, I was going to try expanding the root partition to take up the unused space.) I used Gparted on a CD to do this, as I figured it was safe to do.

I now cannot mount the swap space at bootup (and have to go into a backup version of the OS), although I can use Gparted in Linux to execute the "swapon" command, and it appears that it worked because I now see "swapoff" as an option on the context menu. (I actually don't even need a swap partition, except to hibernate.) If I highlight the swap partition and click on "Drive" on Gparted's menu bar and select "Create Partition Table", it will erase all data on /dev/sda, so how do I fix the bad partition table non-destructively?

Debian Installation :: Wiped Windows Partition With Swap And LVM Partition

Jan 17, 2015

I am having issues with Grub 2 after installing Debian 7.8.0.The computer is a HP Pavilion 500-307nb. I made the original harddrive /dev/sdb and inserted a Samsung Evo 840 as /dev/sda. From the original hard drive (/dev/sdb), I wiped the windows partition, but left all other partitions unchanged (in case I would ever want to recover the desktop to its original state). I replaced the wiped windows partition with a swap partition and an LVM partition.These are my hard drive partitions:

/dev/sda (Samsung Evo 840)

Number Start End Size File system Name Flags
1 1049kB 3146kB 2097kB primary bios_grub
2 3146kB 944MB 941MB ext4 boot
3 944MB 94.4GB 93.4GB host lvm
4 94.4GB 1000GB 906GB guests lvm

[code]....

The partition /dev/sda3 has 2 logical volumes with filesystem ext4 that I mount to / and /home.The partition /dev/sda2 is mounted to /boot..When I install like this, Debian installs fine, however Grub2 is not installed correctly.Debian installs grub-pc which seems not able to boot the gpt partition. So I boot the Debian CD in rescue mode and execute:

mount /dev/sda2 /boot
aptitude purge grub-pc
aptitude -y install grub-efi

After rebooting, I come in the grub rescue shell, which says: error: no such device: 986f2176--4a4b-4222-83b9-8636a034b3c7.

When I then enter in the grub rescue shell:
set boot=(hd0,gpt2)
set prefix=(hd0,gpt2)/grub
insmod normal
normal

Grub and Debian start up correctly.why can Grub not start up automatically correctly? Where does the UUID 986f2176--4a4b-4222-83b9-8636a034b3c7 come from? I have reinstalled Grub several times, I have reinstall Debian several times, I have even wiped all partitions from /dev/sda and recreated a new gpt table with parted and manually set the partitions in parted. Still on each reinstallation, Grub fails because it cannot find exactly the same UUID. Since this UUID is always the same, it must be stored somewhere, but it cannot be the partitions, I have wiped them and the partition table several times.

I did though a firmware update of the Samsung Evo 840 before reinstallation, could this be a cause?Also the problem is not in grub.cfg. Grub starts correctly if I enter the commands above in the grub rescue screen and the UUID value does not appear there.

Ubuntu :: Extremely Slow Swap Performance

Jun 24, 2010

I'm getting horrible (unusable) performance every time swap is accessed. This was compounded by the GEMS leak and a few other memory leaks, but now under normal non-leaky memory usage swapping is still intolerable. For instance swapping out ~300mb when I opened a new program with RAM full resulted in the system nearly freezing up for about 3-5 minutes (however long it took to brew a cup of coffee and come back to the system just finally unfreezing).

Ubuntu :: Swap Partition Access / Cant See That Partition

May 21, 2011

I've recently just installed ubuntu 11.04 but seem to have made a big mistake. During the install process I was asked to specify a location to be used for swap. Not really understanding what this meant I chose another partition on my drive with some free space but also a lot of my data. Needless to say I now cant see that partition. Is there anyway for me to access it? or to at least recover the information I need from there? its about a 200gig partition, and it used to be ntfs.

Ubuntu :: Slow Boot Time - Boot To Bios And Then The Screen Goes Black With A Blinking Cursor

Oct 14, 2010

I've got two laptops running Ubuntu. Both have had Lucid installed from the live cd. I have upgraded one of them to Maverick. Both distributions are running great after they boot up, but I haven't experienced any faster boot times with either distibution. Both boot to Bios and then the screen goes black with a blinking cursor in upper left corner of the screen. The black screen remains for 30 to 45 seconds and then I get the Ubuntu splash screen for maybe 5 seconds, and then desktop. Why am I not seeing faster boot times? I realize 45 to 60 seconds is good compared to other os's, but I anticipated much faster boot times. Shut down on the other hand is quite fast at maybe 5 to 10 seconds. Does anyone else get this black screen on boot? Seems like wasted time cause I can't tell what's going on during the time there is a black screen. This is not a real big deal breaker, as I don't reboot very often, but I just wonder why bootup isn't faster.
