Ubuntu :: Way To Force Ubuntu To Check For Hardware After Boot
Jan 17, 2011
I'm running maverick on a laptop with a wireless adapter which you can turn on and off via a button above the keyboard.If you boot ubuntu with it switched on, everything works fine, you can turn it on and off and ubuntu detects when it is on or off.However if you boot with it off and then subsequently turn it on then ubuntu doesn't detect it and you require a restart for it to work.
Is there a way to force ubuntu to check for the hardware after boot and discover the new adapter in the same way that it does during a normal boot?

When I ran 8.04, force check would be run every 23 boots. The ESCAPE key allowed me to skip it that boot and it would again start force check at the next boot. In 10.04, it gave me an option to use the C key to cancel, but it does not attempt force check at subsequent boots. It does not seem to do an automatic check any more.
How can I restore the original 10.04 setting? Or better yet, get it to perform as it did in 8.04

A colleague of mine was studying at the University of Vienna and saw an application which was based on linux whereby other pc's booted from it and if on the server they had set it to force a clean install on that PC it would download and install a windows image. Does anyone know of the app or could point me in the direction of a similar app.

Have just moved into my gf's place from a shared accomodation and have taken my mythbuntu (8.04) box with me. Have plugged it into her Sony tv and initially it looks promising, bios screen shows and so does the mythbuntu splash. But after that the tv just sits there with a message saying "out of range". Anyone got any ideas how I can force it into a low graphics mode or similar so at the very least I can access the desktop.
Oh and to make things worse my gf has no Internet access (writing this on my phone) and I don't have a livecd to hand

I've installed xUbuntu on a machine I will be using as a file server. Everything is fine except one thing. If the server suffers an improper shutdown such as a loss of power the next time the machine boots it gets to the GRUB2 boot menu and then waits for a keyboard input.As this machine runs headless with nothing connected other than a network cable and power lead and is tucked away under the stairs it's quite an inconvienience to go to the machine and plug in a keyboard so I can press enter.Is there some way I could force the machine to boot as normal without stopping at the menu ?

I'm trying to run ubuntu 11.04 (64-bit) on my hp pavilion tx2100ed but it won't boot. After the grub bootscreen it goes black and doesn't react to Ctrl-Alt F1 ..F4.
Also booting the recovery mode doesn't work
To be able to start the installer I had to use xforcevesa.
Does any one know what this can be and how to solve it?
can i force x to start in vesa mode using grub commands?

I have system (Ubuntu 10.10) on my pendrive. I want to use this system always from this pen - by boot on startup.
If I remove all of my hard disk from laptop and boot from pendrive - everything is ok, but when i try boot from pen when hard disks are plugged - its not working - because linuks want pass to sda2 partition, and this partition is already assign to wrong disk (should be in pendrive).
I have crypt(luks) and lvm on this pen.
I just want to make sure that my pendrive will be always shown as "sda" - how i can do this? I think it will probably fix my problem.
How to disable mount other disk - mount only this pendrive.

I'm having a problem figuring out how to clone and restore partitions from images on a test host, ie. I have different Linux and Windows images in sda2 that I need to restore on sda1 to run tests.
Here's a typical scenario:
1. On a brand new hard-disk, create two partitions, one to hold the OS to run tests, and a second to hold Clonezilla images
2. Install XP in sda1
3. Boot with Clonezilla Live, and save sda1 into an image in sda2
4. Install Linux: It installs GRUB as boot loader in the MBR
5. Save Linux into an image in sda2
6. Restore XP: By default, Clonezilla doesn't restore XP's boot loader, and leaves GRUB to boot XP :-/
How can I force Clonezilla to restore the boot loader in the MBR (while leaving the partition table as-is), so that Linux=GRUB and Windows=NTLDR always?

During startup (suse linux old distro) LILO immediately after stratup procedure I can see login for about 1 sec and then Xserver starts. I'm unable to kill it with Ctrl+Alt+Backspace or Ctrl+F1..So the question is: is there any way I can force linux to boot into console mode before it starts xserver? (I'm unable to modify any files since I cannot reach the consol mode)?Is there any shortcut ky I need to press during boot in order to prevent GUI from starting?

I have updated from Karmic to Lucid not long ago, and everything went smooth and my system is been working like a charm for about a month. And it still does, with the only issue being that every time I restart my system, one of my partitions is checked.
My disk is split into 4 partitions:
sda1, NTFS for windows
sda2, ext4 for "/"
sda3, ext2 for /home
sda4, swap
Now what seems to happen is that sda3 is being marked as "not clean" on every shutdown, which makes me assume that is not being umounted at all.
I've been reading logs, commenting network drives out on fstab.. nothing does the trick.
I've booted into single mode and run e2fsck (which doesn't find anything wrong, and marks the FS as "clean") and then rebooted. The result is: if the FS wasn't mounted when I restart, then I get a clean boot once, but it is checked on the following one; if it was mounted then it is again checked at start-up.
Again, all points to the problem being that the FS is not cleanly umounted on shut-down.
I could not find any log with info of the processes killed and FS umounted at shut-down, so if anybody knows where to look, it could be a good start.

I've been stupid, and used kleansweep, which deleted a load of files and in the process killed everything. When I boot I get "file system check failed". Then it gives me a command prompt. I really don't want to have to reinstall ubuntu as I have a lot of stuff installed on it.

I have recently noticed that my HDD fsck during boot up (generally done after 30 mounts) is always skipped. A file system check has never happened. I don't remember if this is the case ever since I upgraded to Lucid or was it after I tweaked some settings.I am a learner who keeps tweaking some minor settings, so I am not sure if I have screwed up something.At boot I get the following message:
Code:
fsck from util-linux-ng 2.17.2
fsck from util-linux-ng 2.17.2

Every time I boot up I have to go through a disk check and then restart, how do I stop it from happening? When the disk checks happening I press escape and it usually says its deleted inode something because it has zero Dtime or some thing similar and also a paragraph of repeated lines saying something like all system files need alsa base.cnfg it will be ignored in a future release then the disk check completes and it restarts and is fine then, also sometimes it says dev/sda5 (my ubuntu partition) was not cleanly unmounted check forces. Is their a way to stop this happening as it ends up taking ages just to login.

I have a custom modified Ubuntu LiveCD. Sometimes when I boot from the CD, after it detects the HDDs it starts automatically scanning and repairing them even if the partitions are windows partitions. What do I need to modify to make it not scan/repair any partitions/drives at boot?

I just upgraded to 10.04 and it went very smoothly. Only problem is that this version now tries to check a couple of hard drives that are external and not attached to the system. They were set up some time ago and the boot will not proceed unless I manually enter "S" to skip. I have removed folders for these disks that were in /media/... but that didn't solve the problem.

I've just upgraded to Natty. During the upgrade no errors showed. However, when I now boot ubuntu (either recovery mode or normal), the boot process hangs at:
'checking battery state'
I searched for similair problems in this forum, but the solutions in other posts(sudo apt-get update & upgrade etc.) did not help. I'm not sure if it is related or important, but when it hangs, it also shows something like:
'starting automatic crash reporter [fail]'
'not starting jetty'
'saned disabled'
(I can't copy there of course, so it is probably not exactly like this, or in this order...) What can I do to get my ubuntu boot again?

I am not sure whether I ask this question on the right forum. My debian mailserver is depending on a MySQL database. Every reboot it takes around 30 minutes to boot because of the database check. I could not find the right command or setting to boot without this check. Do you know how to do this.

my Fedora 12 does fsck on boot time to time and sometimes it's really annoying having to wait for the check to complete. In Linux Mint pressing <Esc> cancelled the check; however in Fedora this does not work (nor does Ctrl+C nor anything other I've tried). What is the key to cancel the check in Fedora?

What are others' views and experience regarding automatically checking filesystems (running fsck) at boot time?To be more clear, I have left the ext3 filesystems on this machine set to require checking after a fixed number of mounts by using tune2fs with the '-c' option. I've done this mainly because of the following (from the tune2fs man page):
Code:Youshould strongly consider the consequences of disabling mount-count-dependentchecking entirely. Bad disk drives, cables, memory, and kernel bugs could all corrupta filesystem without marking the filesystem dirty or in error.e using journalingon your filesystem, your filesystem will never be marked dirty, so it will not normallybe checked. A filesystem error detected by the kernel will still force an fsck on the nextreboot, but it may already be too late to prevent data loss at that pointBut what does anyone else do? Is there really much risk to disabling this automatic checking

I'm using debian testing with grub2. Is there a way to stop the FS check at boot (something like ctrl-c) after the check has started and continue with the boot process as usual?.

While booting Slackware 13.1 it stops to check sda4 It says something about discrepancies. This started today after leaving the system up overnight. The system was suspended and wouldn't respond. I ended up have to do a hard reboot. The system seems to be working fine, but it does this every time I start Linux. The sda4 partition is Windows XP. XP also is working fine. While Linux is checking sda4 there is a statement that I need to run fsck without options. When I ran fsck I got the following message.
root@b-bhome:~# fsck
fsck from util-linux-ng 2.17.2
e2fsck 1.41.11 (14-Mar-2010)

There are numerous fs checks with transaction log replay at every boot of my opensuse 11.4 notebook.I do not see any error messages on the console during shutdown or startup (but maybe I am just reading too slow)./var/log/messages contains some error messages from NetworkManager during shutdown, but I think they are unrelated.Filesystems I use are ext4 for /boot, ntfs for windows partitions, reiserfs for the root filesystem and for several logical volumes.
As far as I could see the checks are only done on the reiserfs filesystems on the logical volumes but I cannot see any warnings during volume group activation, so it seems the logical volumes are deactivated at shutdown.Of course I do wait until the notebook powers off by itself on shutdown.I'll provide /var/log/messages of a shutdown/boot shortly
Code:
# cat /etc/fstab
/dev/disk/by-id/ata-ST9320423AS_5VH2RFHZ-part7 swap swap defaults

A few days ago I upgraded my debian sid system, and since then systemd does a filesystem check on every boot which takes over two minutes, disobeying the existing settings I had. How can I set systemd to do a filesystem check only once every a set number of mounts, like I had set up before the upgrade?

I'm just curious - why do all linux distros (all I've seen) run their periodic disk checks during boot? I mean, I understand that a disk should be checked now and then, but why does the system do it during boot, when I'm waiting for it to load, instead of checking them during shutdown, when (most probably) user doesn't need the computer anymore.
