Ubuntu :: 11.04 - Cannot Type Since Last Upgrade
Sep 1, 2011
Last time I let my Ubuntu 11.04 to upgrade all its packages, I think a new kernel was also downloaded. Since then keyboard stopped working so that I can press Enter button on the login screen, but after I get the desktop ready I cannot type. The kernel version is 2.6.38 but if I boot with 2.6.35 nothing changes. I can start Ubuntu in recovery mode, keyboard is working there, but I don't know what to do there. When I looked around the settings on a certain menu point (Input settings or kind of..) I got an error message that IBus daemon is not started. I was asked if I'd like to start it, but after starting nothing got better. How could I get my keyboard working again..?

Just upgraded from 9.10 to 10.04 and cannot mount one of my partitions. It is encrypted / decrypted in the following fashion:
Code:
# dd if=/dev/random bs=4k count=1 | gpg -a --cipher-algo AES256 -c - > /mnt/usb/keys/fs.gpg
# gpg -q -o - /mnt/usb/keys/fs.gpg | cryptsetup -v -h sha512 -c aes-xts-plain -s 512 create crypto /dev/md1
# mkfs.ext4 /dev/mapper/crypto
# mount /dev/mapper/crypto /crypto
It has been this way for a long time, survived several release upgrades. Now when I decrypt it, I have to use gpg in one command to decrypt the key to a file, then use cat in a second command to pipe to cryptsetup, as such:
Code:
# gpg -q /mnt/usb/keys/fs.gpg
# cat /mnt/usb/keys/fs | cryptsetup -v -h sha512 -c aes-xts-plain -s 512 create crypto /dev/md1
However, I can no longer mount the device:
Code:
# mount /dev/mapper/crypto /store/
mount: you must specify the filesystem type
This is how it's always been mounted. Well I know it's ext4, so I supplied that and was greeted with:
Code:
# mount -t ext4 /dev/mapper/crypto /store/
mount: wrong fs type, bad option, bad superblock on /dev/mapper/crypto, missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
The only item in dmesg is:
Code:
[78.212761] EXT4-fs (dm-0): VFS: Can't find ext4 filesystem

In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
I had very imp data in d:drive

I just loaded octave. I ran through a few examples of how to implement a script file. Everything works until I get to "plot". When I run the "plot" command I get the following.
octave:2> test1.m
error: can't perform indexing operations for <unknown type> type
sh: gnuplot: not found
Just to double check my work, I ran the following code:
y=[1 2 3];
plot(y);

I just upgraded my laptop (thinkpad T61) OS from Lenny to Squeeze. Everything worked fine out of box except I found when I use pcmanfm or nautilus, I couldn't locate the cursor focus by typing a letter that a filename begin with. It is something I used heavily everyday and I just couldn't lose it. Since it failed in both pcmanfm and nautilus I think it might has something to do with Squeeze.

I keep getting the following msg as I try to upgrade from 10.04 -> 10.10 ... "Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade: E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu
If none of this applies, then please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report." I don't think any of the issues above apply - can anyone offer advice on how to get around or "force " the upgrade

So last night after I got home from the bar I got on my laptop with ubuntu 10.04.
I think I held down the shift key for a while and a message popped up like 'sticky keys' for winbloze.
I hit cancel on the box, but then couldn't type anything after. Not in Gedit, not in firefox, not in openoffice.
I tried holding shift to bring the box back, and no luck.
What to do?

I recently installed ubuntu on my pc in parallel with windows 7 ( I have been running wubi so far ). After the installation was completed I installed chrome and Mathematica ( by using the terminal ). I then restarted the computer. When I restarted ubuntu again I realized that I couldn't type on the Terminal any longer.I can type on anything else, documents, browsers, Mathematica ecc, but, as soo as I try to type over the terminal the mouse pointer disappears and nothing happens. However I can copy paste on the terminal but it is of no use since I cannot use the enter key.

I am using eclipse, and whenever a pop-up appears (like auto complete, error detail, suggested fix - usually triggered by mouse-over) over the text field, the caret no longer types. I imagine the text field lost focus when the pop up appears but never got it back.
I can re-enable typing by either alt-tab, or switch workspace then back. But it is REALLY annoying since I need to do this every 30 seconds. The same problem happens to terminal, tex editor, and many other text fields.
I am using an ACER Aspire ONE (N270 atom, 2GB, Intel GMA945). I noticed after upgrading to 2.6.32 kernel but now I have checked with older kernels, they all have the same problem.

So, I thought I'd try Gnome as the default session. Using System...Administration...Login Screen, I selected Gnome as the default session.
When I rebooted, I see an ititial login screen, but when I click on anything, all I get is a black screen and a mouse pointer.
So now I am trying to switch back to the default. So I reboot, hit esc and drop into a root shell, type startx, and I get back to the default environment.
Now, however, When I try to use System...Administration...Login Screen, unlock does not work. I also tried by using su to change from root to my regular ID, but still, when I click on unlock in the login screen settings dialog, nothing happens.
How can I correct this? Is there a text file I can edit as root that will alow me to change things back to default?

When I go to type in a response to a forum post (in the box you are reading this in if you reply) I lose keyboard input. Nothing happens when I type. If I go up to the upper right hand corner of the message box and Switch Editor Mode then I get the keyboard back.

First, I'm sorry if some one has already posted this but I can't find it. I recently installed Ubuntu 10.04 LTS on my laptop and I have a dual boot between that and Vista. I cannot use Ubuntu for more than an hour or two before it won't let me type in text fields. When this happens, the menues (Applications, System, ect.) stop working also.
I can continue to browse the internet and play music when this happens. The problem can be recreated consistently by using OpenOffice Word Processor. I can not type more than a sentence in OpenOffice before this problem occurs. The only way to fix it is to hold the power button to shutdown.

I loose partial keyboard use after login. At first, I login, and can type about 1 word or so, then typing stops. I can use Ctl + Alt + Del to shutdown, restart or whatever. My volume and play stop, pause keys work when listening to music, but I have no pull downs. I can't use the Applications, Places, or System pull downs at all after the typing stops. However, I can still double-click things on the desktop, and I can also launch some launchers on the top system bar. I can browse the internet but no typing.
I once logged in, and did no typing for a couple hours. I just let it sit. Everything seemed normal until I started typing. Then it stopped typing, and no more pulldown menus. Another interesting fact is, I leave my computer on most of the time. I went away for 4 days and shut down my computer while I was gone. It was working fine when I shut it down, but then 4 days later when I boot back up, this crap starts. I'm using Ubuntu 10.04 on a Dell Precision 670. The keyboard is wireless, but I have recently changed the batteries.

I'd like to find all files of a specific type (as determined by the terminal "file" command) from the command line ... and haven't been able to figure out a way to do so. For instance, I'd like to be able to find all JPEG files in my filesystem, even if their names don't end in .jp*. It would be helpful to be able to combine this with other tests in find, so that I could type something like "sudo find / -atime 0 -size +1M -type adobeflash" or something like that.
I've looked for ways to hook find up to file and tinkered around with a few ideas involving pipes, but nothing seems to get what I want.

I was using Hardy Ubuntu and have recently moved to Lucid and in both distributions I have noticed that alt+f2 (launcher) is very slow to show up when I have a lot of programs open.
Also, when I start typing in the box (alt+f2 launcher box), the typing is very slow (Maybe because it is trying to auto-complete?). I don't really understand why.
My terminal auto-completion is very fast. I have a very beefy machine with lots of RAM.
Has someone else also faced this problem? What is the solution?
Is it possible to replace the default gnome alt+f2 launcher with a different one that perhaps doesn't auto-complete?
EDIT: I'd like to add that launching applications from the gnome-terminal is extremely fast on my machine (less than 1 second). With alt+f2, they take 3-4 seconds and sometimes even 5+ seconds.

A while ago, I installed a windows application (on wine) called Max/msp. I have uninstalled it, and removed wine from my system (deleting ~/.wine as well), but now I'm left with some files thinking they are "Max Externals." How do I fix this/restore to the default file types?
