I have a strange problem. Since the installation of my system, my fingerprint device has been found, but I never intended to use. Months later I wanted to try libfprint and fprintd and successfully compiled it. But when I started the fprint_demo program it said no device found. Then I typed lsusb and saw my Fingerprint device was missing.

Dual PII 400, 512Mb with a Promise SuperTrak 100 IDE Array Controller. At present I have only one drive on the controller, configured for 1 JBOD array. I install FC9 with no problem. New partition is created and formatted, Grub is installed, and then... Grub is found and booted, but then I get:

No volume groups found Volume group "VolGroup00" not found Unable to access resume device (/dev/VolGroup00/LogVol01) mount: could not find filesystem '/dev/root' I can boot in rescue mode, chroot to the installed system.

I have a Dell Vostro 3300, i5 460 processor with a NVIDIA 310M Graphics Card. I'm doing a KUBUNTU 10.10 (Maverick) install with the following results. The Live CD boots just fine to, "TEST," or "Install." Installation goes fine. However, the graphics card being used is the Intel i915. I have tried installing the NVIDIA drivers directly from the, "Additional Drivers," tool and after the reboot I get through the boot screen to the console. I try to manually startx and I get the errors, "no device found," "no screens found." The second install I tried purging and blacklisting the nouveau drivers and entering safe mode. Then using apt-get install nvidia-current. After that, nvidia-xconfig. Same results.
The third attempt I re-installed and this time downloaded the drivers from the Nvidia site (version 256.53). Blacklisted nouveau, remove all nvidia, updated initramfs, etc. The install went fine however I still end up at a console after boot with the same messages as above. No device found, no screens found. I've tried searching through the forum and web and have tried things like adding the modset option along with many other hacks, tips and fixes. still, no go.I can live with the Intel graphics for now although I lose 512MB of memory. Unfortunately there is no way to disable or change this set-up in the BIOS. I've seen quite a few bug reports at Launchpad:
1. Is this something I should just wait til a fix comes? Will a fix come?
2. Is there, or will there be an official Updated Ubuntu Guide for Maverick to install NVIDIA drivers with this tecnology?
3. Lastly, is there anything else I should try??

I have two identical 2 TB eSata external harddisks. Until recently I had them configured as a RAID-1 array. I find that resyncing takes a lot of time, reducing availability too much. Is it good idea to split the disks into 4 partitions of 500GB and use LVM to make them appear as 1 again? The idea is to reduce syncing time to 1/4-th but I might be over-designing here. How likely is it that only 1 partition would need resyncing? Is there a significant performance-penalty when combining RAID and LVM? Is there a simpler solution? How about using notify to automatically back-up essential changes?
I installed debian 4.0 (etch) on an old computer with some pickled graphics card in it, and then I upgraded the computer to one with slightly newer hardware only without the graphics card (the new one used on board graphics). I moved the hard drive from the old one to the new one but when I booted it up it failed to start the X-server and I got some errors listed for "device not found" and "no screens found".
I tried using "dpkg-reconfigure xserver-xorg" however I can't seem to find a working configuration. It seems pretty silly that when installing debian it can detect all this automatically with no problems but when it comes to changing some hardware around you are left in the dark with a complicated re-configuration process. Is there not some way to automate this? I'd rather not have to re-install everything
I've written a bash script to connect to each machine in our local network and update the fstab file to point certain NFS mounts to a new location.The script is meant to read in a list of shares and a list of workstations, rsync the relevant share then connect to each workstation and update the fstab file before moving onto the next share.In reality what is happening is it will perform the loop correctly for the first workstation in the list but will not move on to the next one. I'm really stumped on this and I'm sure it's something simple but I just can't seem to work out the answer!

I just bought an hp 6500 wireless printer, and after taking 5 minutes to set it up (amazing how easy it is to get hardware working that supported by Linux) I was happily printing...But- I haven't managed to get it to scan from my desktop pc running 9.04. Tells me no device is found. I added the printer to a laptop running 9.10, and it scanned perfectly straight away...
I've been through the Ubuntu help documentation and haven't found a solution.I think that maybe Turbo Print (for our old Canon printer) might have messed something up. I had to uninstall Turbo Print to get the printer to work (it hijacked Ubuntu's built in printing stuff).
I just installed Ubuntu to my external drive, but when I try to boot from it, it says Boot device not found.
I have installed the bootloader to sdb (external drive via the installer).
I installed Debian Lenny on my HP Laptop - dv6-2120ed. Because i have atheros wireless card i needed to install ath9k which is not supported in 2.6.26 kernel so i compiled it to 2.6.32. Everything is good, but when i boot the new kernel i get "Bar 6: No parent found of for device" for 2 devices - the ethernet LAN card and the sound card. After 1 minute waiting the kernel starts booting and everything works fine (the LAN and the SOUND card too). How can i fix this and what means it exactly?
I tried with other kernel - 2.6.35 and 2.6.34
I have made linux raid array, named it md1 and it can be found under /dev/md1. I have created single partition (whole disk) of type LVM (8e) and it can be found under /dev/md1/md1p1.
When I run: pvcreate /dev/md1/md1p1
I get this message: Device /dev/md1/md1p1 not found (or ignored by filtering).
But if I run pvcreate /dev/md1
Everything went OK. I can create volume group and logical groups after that.
I haven't found anything specifically on net, except that partition for LVM to work should be of type 8e. Does this doesn't have to be true when we use whole disk as a VG? Should I expect any problems since this is going to be iSCSI target disk?

I installed Ubuntu 9.10 a few days ago, did the updates, surfed on the net, mounted a slave drive and read everything on it, shut down, pulled the slave out and now I can't boot.
After the post screens I get: Verifying DMI pool data
Grub loading
error: the symbol 'grub-device-open' not found
grub rescue>
I think way back I had to reinstall grub or something on another machine I had but I don't remember anything about it. Is that what I have to do and how? Is it because I pulled that slave drive out that this happened? I want to get some more files off the slave as I wasn't finished.
I'm running NetWare SLES 10 sp3 with OES2 sp2. I was working with the folks at Novell to resolve an iPrint Print Manager problem.
During the process they wanted to perform a packet capture using tcpdump. While logged in as the root user the error no suitable device was found, and I received no data at all. This server is running on a VMWare Center. On other SLES 10 sp3 systems (residing on that same VMWre Center), tcpdump captures packets just fine. I inherited all of these servers, so I wasn't here during the initial build, but I'd make the guess that they were configured similarly. On a Server that I built recently, tcpdump works fine. On two of my Servers it does not, and gives the mentioned error.
It's not that big a deal, otherwise the Servers are communicating and working just fine. But, I'd like to get it working just because it's supposed to work. Students are off for the summer, so I have time to play.

Only OSS card is seen in Xfce mixer, and OSS works, but no alsa card.I have a Via82xx onboard chip and a SB Audigy 1 [SB0092], Emu10K1. Via was set up with an alias as the first to load. All this worked perfectly in 13.0. Now aplay gives the following message:Quote:

View 7 Replies View RelatedFedora 14 is used throughout the whole problem. The problem started when I wanted to install Fedora 15 DVD by making a bootable USB key. The size of the USB stick is 8 GB. The problem happened when I (following the tutorial) wrote the line [URL]... livecd-iso-to-disk command associated with the path to the ISO DVD and the partition on the USB stick. the USB stick has the device name /dev/sdb , 1 partition sdb1.
I then noticed that it was mentioned to unmount the USB drive before doing this command. so, while the terminal had written in it "Checking" , I pressed CTRL+C to stop the execution and then pressed on the arrow beside the device in the computer window (Which I think that it unmounts the device). The actual problem started here. I then tried to mount the device but couldn't, It said the device was not found. so I removed the drive and inserted it again, the OS didn't automount the USB drive, I tried to manually mount it but it said the device is not found or doesn't exist. then I used fdisk -l, It said that the sdb didn't have a valid partition table. Also the size of the device is wrongly reported. It should be 8 GB but it is reported to be 2 TB?!
[code]....
I think the wrong partition table made it think that it has a certain number of sectors which isn't real,that made it think that the device is 2 TB large....
