Ubuntu Installation :: Left Shift Key Not Working In 11.04
May 3, 2011
I have been enjoying 11.04, upgraded from 10.10, for the past few days without any problems. Today my left shift button stopped working, or at least changed its behavior. When I run xev, I get 'KeyRelease event, serial 39, synthetic NO, window 0x3c00001,root 0x15a, subw 0x3c00002, time 12813775, (27,34), root94,82),state 0x11, keycode 50 (keysym 0xffe1, Shift_L), same_screen YES,XLookupString gives 0 bytes: XFilterEvent returns: False'
I am using the usa keyboard layout and have not had any problems prior to the 11.04 upgrade. I have also tried creating a new user and changing to ubuntu classic. The problem with the left shift key persists through all of these changes.

I've been having a strange problem with my keyboard lately. certain characters aren't capitalized when I hold the left shift. Right shift covers these buttons, but then ignores some itself.I know that it used to be fine, as I set a password on my router with a capital letter which then did not work, and in my AWN terminal, I would use ctrl+shift+v to paste in lines of code.
I am running Ubuntu 10.04 64 bit, on a Compaq Altec Lansing.For a demonstartion, here is the alphabet as typed holding the shift keys.
Left Shift
ABcDEFGHIJKLmNOPQRSTUvWxYz
Right Shift
ABCDeFGHiJKLMNopqrSTuVwXYZ
Both Shifts
A B ce D ce F G H ,i J K L mu N .o /p zq vr S T mu vr xw xw Y zq
Also, I noticed now that I cannot use the right shift with the Left arrow key to highlight text...

Since F12 I've big troubles with my left shift key.
I've Fedora running on 3 hosts. 2 desktops and 1 laptop. Only on one of the desktops I've these troubles.
If I press the left shift key sometimes shift gets locked. If it's locked, no key can unlock it. Not the left, not the right shift, nor any other key... and I tried them all meanwhile;-)
It's a real shift lock, not a caps lock. After a (random?) time it releases itself without any user interaction. Releasetime varies between 1 and many seconds.
So, only waiting helps. I already followed the wiki entries for debugging keyboard (input-dev) issues. Watching the output of evtest shows exactly the same output for the usual case and the lock case. They both look like this... code...

I use a Kensington Wireless Netbook Mouse.It has worked well in Ubuntu 9.10 and 10.04.For some reason in 10.10 it works, but every now and again it sticks for a second or two. Sometimes the left button stops working.If I pull out the dongle for the mouse and put it back in my mouse works fine.

I got home from work today and my laptop was being strange. normally when left for a while the screen locks so you have to enter your password to use it. when i came to it the screen was black, like normal, only there was no login box just the mouse curser, that i could move about. so i did the ctrl alt f1 thing and logged in then rebooted. booted up all ok but neither of my shift buttons work. they work in the main login when i first turn it on but after im logged in they do nothing. i tried selecting mutiple items with shift and that doesnt work either. i aint changed any settings or owt like that. does anyone know whats up with it and how i can fix it'questionmark' im using 10.04 on a dell inspiron 1525 laptop. when i log in as a guest the shift buttons work fine. what is it that i have thats stopping them from working 'questionmark'

For some strange reason I am not able to highlight/select words using Ctrl , Shift and the arrow keys together. Each of them work individually with the arrow keys but. Is there anyway I can find out if I have assigned a shortcut to that particular combination ? (Nothing is listed in keyboard shortcuts)

I have a Lenovo G550 Notebook, with a US keyboard layout (dedicated Numpad on the right). Now the quirk is.. the 'Home', 'End', 'PageUp' & 'PageDn' keys on the numpad do work in Ubuntu (They double up as 7, 1, 9 & 3 respectively, when Numlock is turned on), but what doesn't is Shift + 'Home', 'End', 'PageUp' or 'PageDn'.. Is there a setting to do this? I just have gotten used to it in Windows (for say, easily removing the typed in URL on a web-browser, using the keyboard), it seems like alls' lost without it

I'm running Kubuntu 10.10, with KDE 4.5.2, what I've noticed is every so often my Tab, Caps, Shift, Ctrl, Alt, Super keys stop working. I'd been running Ubuntu 10.04 with Gnome and hadn't ever come across this issue. I'm not sure if this is related to KDE 4.5.2 or is possibly because I updated to 10.10 and would also occur on a Gnome environment.If I switch to my virtual machine (VMWare Workstation 7.1.2 build-301548 which I was able to get working on 10.10 using URL.... the keys work within that but if I switch back to my host desktop they stop working.To fix it I've found logging out or unplugging the keyboard and plugging it into a different USB port fixes it.

if the computer sits for a length of time, not being used. I have not timed it, but around an hour it seems. All drop downs work, but whatever i click on doesn't do a thing so i can open the drop down to shut down but when i click on it it just sits there or if i try to open firefox or chrome it just sits there. if im browsing the web or playing a game for a couple hours everything works but it i leave it to do something else and it takes close to a hour, and i dont shut it down. It just stops working. then i have to kill the power to stop it.

I did an internet upgrade last night and right around then I think I also got a little liquid around the touch-pad of my laptop and now the left click won't work in Ubuntu on either my touch-pad OR mouse so I am not sure if maybe the connection for the left click on the touch-pad is shorted causing it to stay "clicked" which somehow disables the left click on the mouse... On my windows xp partition(which I am using now) I am able to use the left click on the mouse but still not the touchpad... Anyway I am wondering if there is a way to disable to touchpad via console or some other way to get around this so I can back my important docs and files and then "mouse" it till I can get a new laptop.

I'm having a problem with gnome. When I press a multimedia key on my keyboard (or obstensibly other hotkeys although I haven't figured out exactly what). My left-mouse button stops responding. The right mouse button works fine and the mouse tracks fine. I can go into the mouse control panel and switch it to a left handed mouse and the left mouse button works, but not the right. I ran 'xinput test "HP Mouse"', and I can see the left mouse clicks coming through. So X11 at least thinks it's coming through. I've got nothing interesting that I can find in /var/log. This is really generic USB hardware. HP Mouse and Microsoft Digital Media Keyboard.

After upgrading from 10.04 to 10.10 I have a big problem that makes ubuntu unusable. It seems like my left mouse button has stopped working. Left mouse clicks are not registered (although right clicks are). I've tested with 3 mouses (all USB, 1 wireless, 2 wired) and all show the same problem. All three mouses work fine under Windows 7 on the same computer and under ubuntu on different computers.
Right now I can't do anything, does anyone have a good suggestion how I might go and start troubleshooting this?

I upgraded from 9.04 to 10.04 then 10.10. Now my left mouse buttons doesnt work when I click the pplications menu. Sometimes it doesnt work at all. left or right click. This is very frustrating to say the least. I have seen a few posts that look similiar and have tried what they sugested, but it still doesnt work. I have tried different mice, but it is the same problem. I dont see any error msgs in any logs I look in. Im thinking my next step is to reinstall, which Im not too excited about.

I just installed fc12 on a Dell Latitude E6500 laptop. Everything is fine except that my Left and Up arrow keys are inactive so .e.g. I can't review bash history.
In the "keyboard preferences" GUI the keyboard model is "evdev-managed keyboard" (although I have also tried without success the model specific for this laptop) and the only layout is "USA".
Have done an update of all packages without fixing this problem.

I'm not sure if I should post this question in "hardware & laptops", or "Desktop Environments", because this is a hardware problem on a desktop computer.
Description of Problem:There is another thread that discussed this same problem that I'm having: However that thread is so old that the suggestions in it no longer work in Ubuntu 10.04 and for whatever reason I can not make a reply to that thread.As in the above thread, I've tried other input devices and rebooting the computer and using other USB ports, and my mouse still intermittently double left clicks randomly at times when I've only clicked the left mouse button once and at times and places when it should only produce a single click such as when selecting a drop down menu.
Has any one else had this problem, and does any one have any idea how to fix it or to trouble shoot this a bit more? Please let me know if there is any other information I can provide to further clarify or troubleshoot this issue.

Two days ago, the down arrow cursor key quit working on my usb keyboard. I could go up, or left and right, but not down. I figured the key was broke and pulled out a PS/2 keyboard and plugged it in. Problem seemed to be solved.This morning, the down arrow cursor key again was not working. I thought that was a weird coincidence, so I plugged in the old usb keyboard, and the down arrow cursor key was again working!

I am having a java program which will read characters from console. i have started my program from bash shell and now the program starts and waiting for the inputs. Say I have typed text , "hello". If i try to move the cursor position back wards using the left arrow button it was not working. Instead some junk characters are printed on the console like ^[[C .
hello^[[C^[[C^[[C^[[C^[[C
Below is my program.
public static void main(String as[]) {
BufferedWriter outputWriter =
new BufferedWriter(new PrintWriter(System.out));
[code]....
Note: In windows its working fine.

I would like to use two monitors with my desktop, so connected them the other day and it worked straight away, which is good but... The monitor configuration app always want the primary monitor to be on the left hand side, thus it always extend my desktop right. Can I do anything to extend my desktop to the left instead of to the right so I can have background application on the screen to the left?

The first is about implementing function calls. The way I currently have it is that functions are called with a C++ std::vector of nodes as the parameters. How would I turn a comma-seperated list of expressions into a C++ vector in the grammar?Second, how do you implement left-associative operators in a parser that does not allow left recursion?
And third, what would be the best internal representation of integers? A C++ int seems simplest, but limited. Using GMP seems more versatile, but I'm afraid it might seriously slow down the interpreter compared to C++ ints.

I have a Dell Vostro 1220, with Intel 4 Series Express Chipset Family graphics card. I work on OpenSuse 11.3 (64bit), on the latest kde.I work on an extended 1680x1050 screen on the left of my laptop screen (1280x800). I set this with Kxrandr and it worked great,a while... Now, it shows a black band on the right side of my laptop screen. I can live with that. But the mouse does not recalculate for this difference, so that I need to click 1 inch to the right of where I want to click.
