The "Linux questions (and other stuff)" thread

Here's a question that I don't know. I'm debating one of those.... Tablet laptop things. You know, that you can convert. Anyway, question is.... Does Linux have any touch screen support? Unity would be great on a touch interface I think.

I have zero personal experience with this, so all I can offer is, yes, it exists. Not very helpful, I know!

From my understanding it does that was the whole point of unity and gnome 3
 
I have a Toshiba with a touch screen running Mint, which is based off Ubuntu, and I can use the touch screen just fine.
 
I've never looked for one, and unfortunately I am computerless this week, but I would imagine there is one, possibly under Accessibility settings.
 
Sweet, that's where I figured it would be. I'll have to try this out whenever I get the new laptop. For now though, I think the misses would kill me. I already have four laptops and two desktops....

Awesome. Is there an on screen keyboard by chance?
Click to expand...
There should be lots of those available, and I don't mean in accessibility. The on-screen keyboards for accessibility purposes, and/or for use with a pointer, aren't touchscreen keyboards.

A quick glance in Synaptic yielded several for touchscreen purposes, including:

matchbox-keyboard

on-screen keyboard

Matchbox-keyboard is an on-screen 'virtual' or 'software' keyboard, designed for touch-screen devices running X.

Matchbox is a base environment for the X Window System running on non-desktop embedded platforms such as handhelds, set-top boxes, kiosks and anything else for which screen space, input mechanisms or system resources are limited.

ubuntu-keyboard

Ubuntu on-screen keyboard

Ubuntu Keyboard based on Maliit-Keyboard

Maliit provides a flexible and cross-platform input method framework. It has a plugin-based client-server architecture where applications act as clients and communicate with the Maliit server via input context plugins. The communication link currently uses D-Bus. Maliit is an open source framework (LGPL 2) with open source plugins (BSD).

Ubuntu-Keyboard on-screen keyboard is a Maliit plugin.

Along with calibration tools, such as:

x11-touchscreen-calibrator

X Window System's Touchscreen Calibrator

The purpose is to calibrate the touchscreen's coordinates automatically.

Install this package and it will run automatically in the background of X Window System.

I recently stumbled upon a nifty, handy-dandy shell script called inxi that I really like. If you're not familiar with it, you can read its page at code.google.com. This is from its man page:

Code: 
DESCRIPTION
       inxi is a command line system information script built for for console and IRC. It is also used for forum technical
       support, as a debugging tool, to quickly ascertain user system configuration and hardware. inxi shows system  hard‐
       ware, CPU, drivers, Xorg, Desktop, Kernel, GCC version(s), Processes, RAM usage, and a wide variety of other useful
       information.

       inxi output varies between CLI and IRC, with some default filters and color options applied to IRC use. Script col‐
       ors  can  be  turned  off if desired with -c 0, or changed using the -c color options listed in the OPTIONS section
       below.

PRIVACY AND SECURITY
       In order to maintain basic privacy and security, inxi filters out automatically on IRC  things  like  your  network
       card mac address, WAN and LAN IP, your /home username directory in partitions, and a few other things.

       Because  inxi is often used on forums for support, you can also trigger this filtering with the -z option (-Fz, for
       example). To override the IRC filter, you can use the -Z option. This can be useful  to  debug  network  connection
       issues online in a private chat, for example.

Here's its output on my System76 laptop; there are tons of arguments, so this just demonstrates some of them:

if you use inxi -Fz I think is the command for the full stats.
Click to expand...
From its man page:

Code: 
 -F     Show Full output for inxi. Includes all Upper Case line letters, plus -s  and  -n.   Does  not  show
              extra verbose options like -x -d -f -u -l -o -p -t -r unless you use that argument.
...
      -z     Adds  security  filters  for  IP  addresses,  Mac,  and user home directory name. Default on for irc clients

It's a little weird as far as its arguments go; you'd think there'd be an 'all' flag, but there really isn't. :confused: I still love it, though! :D

ETA: If you have a certain set of flags you use most, stick them in a shell script and use that in place of the real inxi. Or--and make a backup copy first!--edit /usr/bin/inxi to your liking.
 
Moody, it's misreading your cpu speeds. An i5 cpu should not be running at 800mhz normally. Idling, yes, but the other 3 processor speed steps are also reading 800mhz.

Not sure if it's a kernel or inxi bug.

Okay, any quick hints how to boot into my home partition using a USB drive? It seems Toshiba borked my boot partition.
 
If it's an UEFI board, you can get into an EFI shell and manually navigate to the the grub.efi boot loader. Not sure what the exact filename is off the top of my head.

Otherwise, boot into any live iso, chroot into the broken install, and reinstall grub from there.

Well...since you asked... :D

Here's cat /proc/cpuinfo followed by inxi -F for comparison purposes:

Ah-ha! Discrepancies! :D

Cpuinfo reports 4 cores, yet inxi reports a dual-core. Additonally, Cpuinfo reports that the stock clock is 2.6ghz, but each core is idling at different speeds, whereas inxi now shows roughly 2600mhz on processor step 3, but 800 for the rest.

Hopefully your processor actually does ramp up to full speed when you throw something demanding at it.

-edit-
Misread the output at first. Fixed post to reflect reality. :p

Can't get an EFI shell on this model... It looks like they emptied out the UEFI boot partition.

If I recall correctly, partition 03 is my boot partition, and if I can boot into Mint 15 I can rebuild that.

I use rEFInd for my bootloader.

Question: Did Toshiba attempt to do a Win8 Reset as part of their "warranty service"? If so, a side effect of that is that the EFI partition is nuked and rebuilt with microsoft as the only entry. the /ubuntu folder should be gone, as well as grub and rEFInd and its dependencies.

Regardless, I have a pretty slick plan: :D

You can mount the EFI partition as a drive from win8.x using diskpart. Here comes the slick part -- if you've ever made a backup of your EFI partition, then go grab it and paste in there. Use diskpart to then unmount the partition (or keep it, if you like the extra way in), reboot, and you're back in business.

If not, you'll have to go for the tedious plan: :(

If you don't have a backup, you'll have to go through the motions of using an iso to chroot into your linux installs and re-installing grub, targeted at /dev/sda3 (assuming you are correct about it being the third partition), followed by the standard update-grub shenanigans. :cool:

Once you've got mint bootable, reinstalling rEFInd should be next, and you probably already know how to do that.

Finally, at the end of everything, you should take an entire backup of your EFI partition so that if this ever happens again, you can just do the slick plan and be done with it in like 10 minutes. ;)
 
Thanks, Joel.

Turns out it was my own damn fault: I used the command efibootmgr to set the laptop to boot from Win so that the Toshiba techs wouldn't be 'confused' by my rEFInd menu.

Had a heck of a time returning things to normal because I couldn't remedy it through Windows and my Mint 17 boot USB drive didn't have the command natively.

I had to boot into the Live USB, get a wireless connection, and then install efibootmgr, mount the boot partition which was more-or-less invisible, and issue the command: sudo efibootmgr - o 0005

Mind, x0005 is the hexedecimal ident for my rEFInd bootloader. By calling sudo efibootmanager without any switches, one can get a list of available bootloaders.

This is one of those times where, when you realize you caused your own problem, that the only response is the Picard Facepalm. :D

Here's what I have. rEFInd has nearly a dozen entries, due to backup copies of kernals that OSs like to spew all over one's hard drive (MS is no exception-- there must be six copies of Shellx64.efi lounging around in the boot partition).
