Non root user variant I would like to suggest a variant for the unprivileged users, since not always it's possible to execute commands as root (some users simply cannot and however it is always a good practice to avoid to run commands as root when it's not needed), or there is no will or possibility to install new program: cat ...

Don't reboot directly but first shutdown then start it. This is probably some driver problem. Hope it helps!

sudo apt-get purge bcmwl-kernel-source and then sudo apt-get install firmware-b43-installer and reboot. If it doesn't work after reboot add the results from lsmod | grep -e wmi -e laptop

Looks like Windows doesn't reset all its settings when it shuts down and the warm boot of the tablet doesn't either. (I predict this never happens when cold booting) So to "reset" the mouse the best is to file this as a BIOS bug to the manufacturer, (or upgrade the BIOS if one is available) but in the mean time, do the following: When it works, do an lsmod ...

If you want to script this, you can use this to edit the file /etc/default/grub from the script: # Speed-up Grub boot, but always show the boot menu. sudo sed -i 's/GRUB_TIMEOUT=[[:digit:]]\+/GRUB_TIMEOUT=1/g' /etc/default/grub sudo sed -i 's/GRUB_HIDDEN_TIMEOUT/#GRUB_HIDDEN_TIMEOUT/g' /etc/default/grub sudo update-grub This will set the grub menu ...

Does your BIOS allow you to ignore the position of the switch? If yes, use that! If not, try a life-hack: massage the switch a bit until it does work. If that helps, be aware that you have a hardware fault and that in the end, you'll probably have to dismantle the machine to fix it on the "on" position! To help you with that, google for the machine's ...

You could try to use input-kbd from the input-utils package: $ apropos input-kbd input-kbd (8) - print or modify keyboard maps for input devices Using the input device index (e.g. 4 for /dev/input/event4, which can be found via lsinput which is necessarily different than the id used in xinput), you can reconfigure the keyboard map by feeding it a ...

To disable the gestures, you can change the button mapping with the evdev driver so that the last 6 "buttons" are all disabled like so: appending the following to /usr/share/X11/xorg.conf.d/10-evdev.conf or /etc/X11/xorg.conf.d/10-evdev.conf depending on what you have: # custom for Logitech Ultrathin Touch mouse Section "InputDevice" Identifier ...

"dmidecode" is a handy native linux command which gives many hardware details. I've written a script to get all the details and if someone is interested can check out here: How To Get Hardware Info Thanks, Mssm

I wrote a shell script to gather all possible hardware details on Linux systems, including Ubuntu, using native commands. Anyone interested can view and download the script from: A simple shell script to get hardware info from a Linux box. This script fetches the following details: Operating system (Linux) release version, kernel version, uptime details, ...

Installing Ubuntu on the SSD will actually show one of the biggest improvements in snappiness and overal loading times. Not everything is stored in the RAM when it boots, just the programs that it currently uses. Because RAM is just a relatively small amount of storage there is a lot of swapping going on between the hard disk and the RAM. Having a faster ...

Not everything is loaded onto the RAM. Only the kernel and a few other processes are loaded on boot. All the directories in the root filesystem / will benefit from the faster speed of the SSD, which include the applications that you install (in /usr). In fact it is therefore recommended to mount the / on an SSD and the home partition /home on an HDD to ...

The sysfs rom file allows you to read the PCI ROM contents, but apparently the device does not expose that information. It is not available or not implemented by the device. About why ethtool -e eth0 fails, the current r8169 driver (up to and including 3.19-rc3) does not implement a method to read from the EEPROM. If your Realtek network device has an Atmel ...

I know that this is incredibly old but I've run into the same issue and no where has an answer of any kind. To fix this problem I installed sudo apt-get install libao-ocaml-dev and that seems to have fixed my problem. My symptoms were that I could play music if I was root but would the error described by OP if I wasn't. I needed to compile cmus from ...
