I just replaced my RAM, and searched for the best way to do a memory test in Ubuntu. I ran across this page:
[URL]
...which says:
Quote:
Turn On or Restart the system Hold down Shift to bring up the GRUB menu. Use the arrow keys to move to the entry labeled Ubuntu, memtest86+ Press Enter. The test will run automatically, and continue until you end it by pressing the Escape key
Allow the test to run for at least one full pass
So I did exactly that. The GRUB menu appeared, but I had no keyboard control, and thus couldn't select anything. I've tried rebooting several times with different keyboards, and they all show 3 green lights at the very beginning of boot, but become unavailable by the time GRUB appears.
So I booted to a Live CD and the keyboard worked just fine inside that session. But it's still gone during boot. When I'm booting without a CD in the drive (booting to the internal HD as usual), it goes straight to the GRUB list, with no keyboard control, and I'm stuck indefinitely.
how to either bypass this stuck GRUB screen, or somehow restore normal keyboard functionality during early boot?
Using VMWARE Fusion 3.01 on Macbook Pro 15", C2D 2.8Ghz, installed Ubuntu 10.04 on a virtual disc, no problems installing. boots up, offers me my mac username/password logon, but no keyboard entry registers, Cursor is in the password box, tried external PC keyboard, same lack of keyboard enry. So deleted Virtual disc.
I use Debian Squeeze and I'm experiencing a problem that did not occur in Lenny. The app numlockx is capable of turning my numlock on and off, but it can not change my keyboard led status.
For example, if my numlock is off and, consequently, numlock led is off too, when I run "$ numlockx on" the numlock starts working just well, but the led remains off. The same happens if numlock/led is on and I run "$ numlockx off", the numlock stop working just as expected, but the led remains on. it seems numlockx 1.1-10 (Squeeze version) can effectively change numlock, but it can't change keyboard led.
I have a computer whose display I want active all the time, but that I don't want people coming up to and doing anything on. At the same time, I want the keyboard and mouse to remain connected because even though they will seldom be needed, when they are needed it's important that they be available quickly.I guess I'm looking for a screensaver that doesn't save the screen. Something that prevents the mouse and keyboard from doing anything unless a PAM authentication is entered, just like a screensaver would
I've had Ubuntu 9.10 x64 installed on my Asus G60JX-RBBX05 Laptop for a few weeks now, and for the most part its been working pretty well.Then a couple of days ago, I suddenly noticed I could no longer use the numeric keypad. This seemed completely out of the blue, but its possible I received an automatic Update through the Update Manager that hosed it or something. I'm really not sure.Has anyone had a similar experience
I installed Ubuntu 9.10 on a new acer emachine e525. All is fine except that now I cannot switch the wireless on as the button above the keyboard no longer functions. Can anyone tell me what I can do to fix this as wireless is obviously vital in a laptop. BTW the wireless waqs working fine while the machine had Vista on it.
I bought this not too long ago and it worked great in my ubuntu 8.04 install. When in windows I decided to pair the bluetooth combo with a different bluetooth dongle. After changing it back to the original MS dongle (which I used in ubuntu) the keyboard no longer responds in ubuntu. It works in the CMOS, it works on my windows computer, but not in ubuntu anymore. Mouse works fine, and so does the touch pad on the keyboard.
Is there any way around this? I've tried re-pairing, and waiting a very long time...
I have new install of 11.4 X86_64 which has been working fine up until this morning. Now when I boot and get the kdm login screen, the keyboardis no longer working, nothing appears from typing, no key sequences are recognized. The mouse works fine and when I go Console Login, the keyboard works fine.The mouse and keyboard are both Logictech wireless using the Logitech unifying usb link. As I said, it was working fine until this morning.I have no idea how to even diagnose this.
I installed Archlinux yesterday on my Aspire One netbook. I installed fluxbux window manager with the ROX file manager/desktop manager.Everything was working fine until I was walking through a guide to set up the Fn keysto use the keyboard hotkeys for changing the brightness and audio settings here: [URL]I used xmodmap to set additional short cuts. Every since, I can't use my keyboard when I run 'startx'. My laptop touch mouse is working but I noticed the cursor speed has slowed down drasticly since I input the above changes.
I tried putting in 'setxkbmap no' in my ~/.xinitrc, 'no' was the language which is set up in my /etc/X11/xorg.conf and was working before. I also reverted to a back-up of my xorg.conf which I had saved a few hours before, which also didn't work.What could the problem could be here? How can I ensure my keyboard is being properly initialise when I start up Xorg/fluxbox?
I've just upgraded (finally) to 10.04 desktop, and when I boot, I get a login screen, which is quite usual, but once I log in, the machine drops to terminal, instead of the usual GUI. I've tried running startx, but I get this error message. Fatal server error: Server is already active for display 0 If this server is no longer running, remove /tmp/.X0-lock and start again.
This is regarding the PPC machine in our lab, the OS running is Linux. Since we dont know the root login and password, we couldn�t login to this PPC machine. We tried to login as using single user to reset the password however when we reach the single user prompt, inputs from the keyboard are no longer recognized and the machine freezes.
Computer: Toshiba Satellite Pro L510 laptop, 10.10.This has always happened but I have gotten around it by time-out and putting my menu.list in order. When I first boot the machine (switch on for the day from computer being off) I get to the grub options to select a kernel and I have no keyboard. No up/down arrows so have to go with the kernel on top of the list (not always desirable).
When I get to the log-in screen if I hit restart and go back to the grub screen I have a keyboard and can select any kernel. If I login to the kernel I have full keyboard, no problem. If I then restart, I have keyboard at the grub list.
Nutshell: It is only when starting the computer fresh that the keyboard is dead at grub menu (and then only). Any time after that, once the computer has been switched on, if I restart I have keyboard at grub menu and can select different kernels. (Of course, if I switch the computer off and back on again, no keyboard ...)
how to setup an Active/Active Load Balanced and High Available (If one of the nodes is down the system still runs) MySQL cluster. I have found quite a few howto's but I have some things unclear in my mind. I found a few solutions like this one: [URL] or this: [URK] Those are using two or four MySQL nodes, two Load Balancers to avoid a single point of failure but only one MySQL cluster management server. What happens if the MySQL cluster management fails?
I have also found a "MySQL Master-Master Circular Replication" technique but from what I read, with this option there is a chance that conflicts will arise if node A and node B both insert an auto-incrementing key on the same table.
Is it possible to map the same "Present Windows - All Desktops" action which is invoked by activating the top left corner of active screens via a keyboard shortcut? I basically want to ape OSX and have an expose-like button, the screen edge works fine for now, but I would love a keyboard shortcut also. Is it possible? Also, when I set up a custom keyboard shortcut to run yast, I initially tried using the same command from the KDE menu: /usr/bin/xdg-su -c /sbin/yast2
However, when I use the keyboard shortcut to launch this command, I get problems when trying to use zypper after the initial launch using the keyboard shortcut(from yast GUI or CLI). The error basically states another instance of yast2 already exists. The problem is only with the app/repo management modules though; for instance I can launch yast (using keyboard shortcut or start menu) and access hardware info, sudo users etc, I just can't access software/repo management stuff. Even when I kill the offending PID from the CLI I still get the error and have to restart the box to rectify it proper. So I changed the keyboard shortcut command to : /usr/bin/kdesu /sbin/yast2
and this seems to have resolved the problem. My second question is what is the difference between the two in this particular instance and why does one cause problems (xdg-su) and the other does not (kdesu).
I have (had) a dual boot computer;Win XP and Ubuntu 10.10 64 bit.I decided it was necessary to enlarge my Root and Home Partitions. Using the instructions http://ubuntuforums.org/showthread.p...ome+Partitions I successfully enlarged the partitions and restored 10.10 (I used the copy command suggested by Irony). However when I boot the computer it boots to Ubuntu but no longer gives me the option of going into XP(it is not listed in Grub menu). Is there a fairly straightforward way of getting XP back on the Grub menu so I can boot to XP again?
Most of my experience configuring network settings has been through various GUI tools available in GNOME and KDE. I have some older hardware that will not run KDE or GNOME and I am trying to configure the NIC. I have installed Webmin to try to configure the interface, and it does fine for setting a static address or DHCP address, but the interface (eth0) is not active at boot.
As soon as I run ifup eth0, it will use the assigned IP or pull DHCP based on settings, but I can't seem to get it to automatically activate at boot. And yes, /etc/sysconfig/network-scripts/ifcfg-eth0 does have ONBOOT=yes set. I need two things...
1 - are there any good cli tools, ncurses or such like netcfg I can install to manage the interface (I have tried the network manager cli tools, maybe I just don't get it, but that isn't working so good for me)
After a long time, I hit the wall. I upgraded my server from Fedora Core 9 to 10 through yum. The first 2 days it worked happily but the 3rd day I started getting the feeling of being doomed. Bad Magic Block started haunting me and due to several services being failed, I had to restart the server. That was the last time I saw it alive.
During boot, my 34 LVM partitions are active but its not able to mount /dev/root. I did the checked the grub and its fine. I tried rescue CD but still can't utilize most of the lvm, vgscan, vgchange commands as it gives me same 'bad magic block' error. My /proc/partition and /sys/block shows me that only 3 out of 5 HDD are active. how to resurrect the OS?
I just did an apt upgrade and for the most part everything is looking good. However when I boot up I have no network connection. Here is the result of trying to ping google: connect: Network is unreachable
I can fix it easily with a simple sudo dhclient eth0 but I was hoping someone would be able to suggest a more correct and less annoying solution. I have uninstalled network manager. This is a desktop computer with an ethernet connection and DHCP. I do not need anything fancy.
I am trying to sort out some issues following an upgrade from F12.
I have eth0 as the connection I want to use. Prior to the upgrade, this connection was enabled and active at boot.
Now, for some reason after the upgrade it has to be manually enabled at every boot - even though when I go the Network tool, Ethernet Device > General tab - "Activate device when computer starts" is checked.
At every boot time it is inactive.
In all the ifcft-eth0 files, the ONBOOT parameter is set to "yes".
My mum has a computer that has a dual boot with Windows XP and Ubuntu 10.10. Well Ubuntu will not boot anymore, i just get a bunch of CLI output mentioning missing stuff. But she has really important data that she needs which is on the ubuntu partition. I have tried using Ubuntu & Knoppix live CD's the mount the partition and copy the data to her external HDD. On Ubuntu it couldn't mount, it just kept trying and trying forever. On Knoppix it just gave me a heap of CLI output that I have no clue what it means. How can I save all her data? Is there a program that can sav the data, or what is the best way?
I had been dual-booting Ubuntu and Windows 7. Today I upgraded to Ubuntu 10.04 and now Grub still has a Windows 7 boot option, but when selected it goes to a blank screen and does not boot Windows 7 as it would before.
I booted my laptop up this morning to find that Ubuntu 10.10 will no longer boot. Here is some background. I have a Raid 0 setup with sda and sdb. For the last day or two upon boot, it was asking me to run some file system checks (hind sight I should have just sucked it up and wait for it) but I canceled out of them as I have been extremely busy. Also, I upgraded my kernel to the latest available from the repos. I am not sure if the kernel upgrade has anything to do with it or just coincidence. I have booted up with a live distro on a USB stick and here is what I am seeing:
Code: root@bt:/dev# ls -alh sd* brw-rw---- 1 root disk 9, 127 Dec 2 10:44 sda brw-rw---- 1 root disk 9, 126 Dec 2 10:44 sda1 brw-rw---- 1 root disk 8, 16 Dec 2 10:41 sdb brw-rw---- 1 root disk 8, 32 Dec 2 10:41 sdc brw-rw---- 1 root disk 8, 33 Dec 2 10:41 sdc1 brw-rw---- 1 root disk 8, 34 Dec 2 11:06 sdc2 brw-rw---- 1 root disk 8, 37 Dec 2 10:41 sdc5 root@bt:/dev# fdisk -l

Disk /dev/sdb doesn't contain a valid partition table Disk /dev/sdc: 16.1 GB, 16125001728 bytes 255 heads, 63 sectors/track, 1960 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00004790

So I am able to see sda in /dev but fdisk does not see it. When looking at gparted, it only is able to look at sdb and sdc (my usb stick). The weird thing is that I also have Windows 7 installed on this raid and it is able to boot without any issues so I know the entire sda hasn't died on me.
I installed ubuntu onto a 20gb partition I created on my Macbook pro. Installation went great, but now I can no longer boot into my Mac partition. When booting up if I hold the option key, all that shows up is a lock icon with a white area below which I can type things into. Nothing happens if I do, and there are not hdd showing. The Mac partition is an option on my grub menu, however it hangs when selected and does not end up loading.
Note: I am on vacation from school at the moment and my live cds for Mac are in my dorm.
This is an Arch / Win7 dual boot. I've got a bluetooth keyboard and mouse. The mouse is persistent across boots but the keyboard needs to be rejoined every time.
My ubuntu(10.10) installation takes a relatively longer time (90 seconds) to boot. I think part of the problem might be related to an error message during boot related to usb drivers. Code: [2.717076] usb 4-1: new low speed USB device using ohci_hcd and address 2 [3.244051] usb 4-2: new full speed USB device using ohci_hcd and address 3 [12.029046] /build/buildd/linux-2.6.35/drivers/hid/usbhid/hid-core.c: usb_submit_urb(ctrl) failed I have attached the relevant part of dmesg output also.

Everything went fine but whenever I rebooted, Ubuntu 10.10 was not an option in the boot list. However, Windows shows up and boots just fine. I am currently tri booting (not sure if that's the correct term) Windows 7, Ubuntu 10.10, and OpenSuse each on a hard drive of their own. In the dolphin file manager I can still see all the files for Ubuntu so I know it was not partitioned over or deleted.
