lsub in Ubuntu server 9.10 does not see my Brother HL2140 printer
location: linuxquestions.com - date: December 5, 2009
Here is a truly newbie question that has been baffling me for the last few days: I bought a Brother HL-2140 usb laserprinter and am trying to add to my ubuntu 9.10 server. So, the first step is to physically connect it to one of the usb ports and use lsusb to see if the printer is being seen:
Ubuntu 12.04 LTS (64 bits) does not boot after RAM upgrade
location: ubuntuforums.com - date: October 3, 2013
I've successfully installed Ubuntu 64-bit on a Dell Latitude E6510 with 2GB of RAM. Looks great! It is my plan however to run a virtualized windows 7 on top of Ubuntu for the programs which absolutely need windows (e.g. Outlook) and for this I've upgraded the RAM space to 8GB.
After the upgrade Ubuntu does not boot and ends in a panic: early exception 08 rip 246:10.
It does want to boot however when I add the boot command "mem=2048m", but this is off course not my intention. I've also upgraded the BIOS.
Another interesting thing is the result of the memtest86+ program. It fails with a memory error: too small lower memory.
Any ideas on this one.
Thanks in advance,
ubuntu partitioning tool does not see external usb hard drive when installing ubuntu
location: linuxquestions.com - date: July 29, 2006
My friend's usb hard is not showing up in the Ubuntu installer when I get to the part with the partitioner. If I do "sudo fdisk -l" the hard drive does not show, but "lsusb" does show it. How can I use the external usb hard drive? I will find out what the model number and who makes it is soon, but I won't know for a few days.
[SOLVED] Ubuntu 10.04 LTS in laptop Acer Aspire 5750G does not see wired internet
location: linuxquestions.com - date: September 19, 2011
Laptop has two-boot system, Windows 7 and Ubuntu 10.04 LTS. I before installing 10.04 I tried Ubuntu 11.04 from CD, it did not work at all (screen was black), so I've installed 10.04. The installation went smoothly. However, internet is NOT achievable under Ubuntu, while works without problem under Windows 7. I'd appreciate suggestions how to force the laptop to discover the internet wire.

SSH dynamic port forwarding Firefox does not see such a PROXY
- date: May 1, 2005
I have two machines on my network ('Client' and 'Server'). Both are Debian Sid.
Server is connected to the Internet. NAT, IP masquerading are NOT configured -- so there is no connection to the Internet for Client.
I'm trying to setup a SOCKS server on Client using SSH dynamic port forwarding.
:$ ssh -D 1080 [email protected]
The idea is that any SOCKS-aware program on Client can use this localhost:1080 as proxy to connect to the Internet.
My problem is that not all SOCKS-aware programs on Client agree to use this proxy. For example, putty for Linux works fine when I tell it to use SOCKS 5 server on the address localhost:1080.
But Firefox and Mozilla just do not see this proxy, although I configured them as follows: Edit-->Preferences-->General-->Connection-->"Manual proxy configuration"-->"SOCKS host" localhost:1080.
Grub2 does not see other linux distros
- date: August 10, 2012
Grub2 has been acting strangely over the last 2-3 weeks. I have 12.10 installed on a laptop with two other distros and I installed the 12.10 grub2 as the bootloader.
Basically, grub sometimes sees and sometimes does not see one of distros (on sda3) and never sees the other one (on sda1). Quantal itself is on sda5.
I wrote a couple of very rudimentary scripts custom entries in /etc/grub.d and if I press Shift to open the boot menu I can access sda1. Sda3 refuses to boot so there's something wrong with that script.
Here's the result of fdisk:
:~$ sudo fdisk -l

OS does not boot with LVM and custom kernel initramfs
location: ubuntuforums.com - date: August 26, 2013
Q.The problem is on boot grub doesn't fully start the OS. Theelement that appears to be the problem is LVM. Thekernel can not see the root partition.Why am I doing this: I need to build a custom kernel fromkernel.org for some video drivers to work. Just need someone to pointme in the right direction to get grub2 and LVM to get working. The hand-off is the issue. Fyi: no RAID is being used.
I. I have placed the boot partition outside of the LVM.
I have three partitions:
$ fdisk -l /dev/sda
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 499711 248832 83 Linux
/dev/sda2 501758 976771071 488134657 5 Extended
/dev/sda5 501760 976771071 488134656 8e Linux LVM
$ ls -la /dev/mapper/*root
lrwxrwxrwx 1 root root 7 Aug 2514:55 ubuntu--vg-root -> ../dm-0
Everything with the stock Ubuntukernel works great.
And pvdisplay, vgdisplay,lvdisplay list all the correct stuff.
PXE boot of 2.6.35 does not see Intel Pro/1000 adapter, disk install does
location: linuxquestions.com - date: August 19, 2013
I'm trying to PXE boot a 2.6 kernel, but am not seeing the network card once Linux is booted.
Why? I'm trying to use the fog imaging software, and the latest release (0.32) ships with an initrd which works with this kernel.
I've tried to build an initramfs without successfully booting (uncompress initrd, mount, cd into mount, create cpio archive, gzip cpio archive). I don't really know why that doesn't boot, since the errors go by too fast. I suspect it is failing to mount the root fs.
Anyhow, back to 2.6. The kernel which is supplied with fog (an older 2.6) does not boot on our hardware. I get a green screen. I suspect this is some sort of a driver issue.
I have built 2.6.35 locally, and the necessary drivers are included. This kernel does boot! But the network is not seen. Now when I look through dmesg output I see the Intel Pro/1000 driver load, but it doesn't see the hardware. I have compared this output with that from a machine with 3.9 installed on
IVTV Does Not See Tuner for PVR150 Card
location: linuxquestions.com - date: April 22, 2006
I've tried to install MythTV and ran into problems. Then I tried TVTime to see if I could view TV without getting too fancy.
TVTime gives me an 'Invalid Argument' message and 'Cannot open capture device /dev/video0.
Mplayer just gives no picture with static.
Can you give me any suggestions? I'm running Ubuntu Breezy on AMD64. Thanks.
This is the output from dmesg:

Grub2 does not see newer kernels (3.0.015 and 16) on boot
location: ubuntuforums.com - date: February 22, 2012
I installed another distro on one of my partitions (sda6) and when I tried to make grub to see it I realised that it does not see the newer kernels that Ubuntu updated to either.
Basically when I boot I get the boot menu with Ubuntu 11.10 and the 3.0.0-14 kernel, a couple of older kernels (13 and 12 I think), I can also see Mint, a bunch of recovery options & memtest, and also the distro that I replaced on sda6 (I used to have Ubuntu 10.04 there, now it should be gone but isn't and the new install doesn't show).
Here are the results from boot info script
