Terminal content remains on screen without being 'refreshed'

I'm using Awesome wm and I get this weird terminal/vim behaviour.
Basically it seems to not 'refresh' some lines of the terminal after a command - hence they 'remain' there and I literally have to 'overwrite' the content to remove it.
Here is a screenshot - look at the last line in the terminal window.

Any idea what is causing this?

If you are using bash as the shell, you can try adding this line to your '~.bashrc':
shopt -s checkwinsize
From 'info bash':
'checkwinsize'
If set, Bash checks the window size after each command and, if
necessary, updates the values of 'LINES' and 'COLUMNS'.
Edit: I don't use zsh, but googling suggests it will work there, too.

Is it possible to view website on screen without being in a browser? I want the website to take up the whole screen.

Hi,
I was wanting to use my DW website as an interactive
portfolio for an interview. What I want is to have my website on my
laptop screen so that the interviewer and I could browse through my
website on screen without being connected to the internet, or
having to preview it through a browser, but instead so that it
takes up the whole screen, is this possible?
My interview is tomorrow (eek) so a prompt response would be
much appreciated,
Thanks

If it needs a server, install apache on your laptop, its free
and fairly
easy to setup and install.
As for running full screen, open internet explorer and press
F11 to put it
in kiosk mode, it will show the website full screen. (press
F11 to exit
kiosk mode again)

Why the screen flickers and moves from one app to another by itself without being touch?

Have you tried a reset to see if that fixes it ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

No. Get it fix by making an appointment with the Apple genius bar.

When I restart I get a screen asking to restore the last sesion or start new, how do I set it to start new each time without being asked?

When I close a session I close all the tabs first then exit out. The next time on I get an error screen telling me everything didn't close right and asking me if I wanted to restore the old tabs or start a new session. I am not interested in restoring the old tabs as I want to start a new session. If the old tabs come up I have to close them out anyway. How do I by pass that error screen and just restart a new session automatically going to my home page without all the extra tabs and without being bothered about it? Never had this problem with the older versions. Maybe I should go back to the older versions and forget about any updates. But I don't know how to do that.

This can be a problem with the files [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
Delete [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]

If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.

my droid razr's screen is broken and not responsive. I want to delete the internal memory, passwords, pictures, ect before sending it back to verison in exchange for the warranty replacement.
Thanks

Hi mountain444!
Sorry to learn of the fate of your RAZR. No worries, I can help you erase the device. You would simply do a master reset. I know you can't see the screen, and this is why there is a Preferred Method for this, as well as an Alternate Method. Please follow the steps for the Alternate Method listed below. Thanks!

My volume doesnt work and when i press the volume button it shows the headphones volume on the screen without any headphones being plugged in. what can i do to fix this?

My volume on my iPad doesnt work, when I press the voulme button it shows the headphones volume on the screen without any headphones being plugged in. Is there a fix for this?

Try going to settings> general > reset> reset all settings. If that doesn't work. Place a headphone jack in there and just pull it out a couple times. The problem is either your iPad setting is stuck or there is actually a hardware problem and moving the jack in and out might fix it

Welcome to the Apple Community.
Try deleting the problematic tune (electing to remove original file if/when prompted) and then re-downloading the file from the iTunes store.
You can re-download content purchased from the iTunes store (availability varies depending on location) using the purchased option from the Quick Links section in the top right corner of the iTunes homepage in your iTunes application on your computer.
You can re-download content purchased from the iTunes store (availability varies depending on location) using the purchased option at the bottom of the screen of the iTunes app on your iOS device.
If the problem re-occurs, select the content which is causing a problem and use the 'Report a problem' button in Your Purchase History using your computer.

Login Window: Screen does not refresh correctly after waking 10.7.2 iMac and MacBook.

I have a client who brought to my attention that when we wakes his iMac and MacBook after the screen dims or sleeps at login screen, that sometimes the screen does not refresh correctly and you must use the cursor to basically "clear the screen." I have witnessed this myself and elimiated all third party products and this still happens. I am starting to believe that is is a bug in 10.7.2. Has anyone witnessed this or have any suggestions on how to remedy? Thank you.

Thanks lynque. It turns out I did need a keychain repair, but that didn't fix the problem. I probably should have done this earlier, but I ended up unplugging all peripherals (2 firewire + 3 USB) then powered up without issue.
So I shut down, plugged in one at a time, and ran into the problem again after plugging in an external hard drive (WD My Book Essential). I repaired with disk utility, but the problem remained.
I then rebuilt the partitions with Disk Warrior, and now everything seems to work....

Aspire V5 Laptop won't start and I can't fix without being an administrator

I did a system restore from a recent restore point. After rebooting, my laptop started normally, but then a message came up saying "Preparing Automatic Repair." After a few moments it said "Diagnosing your PC". Then a blue screen came up saying "Automatic Repair." There were two options, "Restart" and "Advanced Options". Restart didn't work (I tried several times), so eventually I tried the Advanced Options. From Advanced Options, I went to "Troubleshoot," and then a different "Advanced options". From the Advanced Options screen, there were several choices that looked promissing; but almost all of them say I need to be an administrator and won't let me continue. To start with, I am an Administrator on my machine, but it says it can't find any Administrator accounts. How can I get past this? My computer is useless and my only options seem to be refresh or reset. Why do I have to be an administrator to save my computer? Please someone tell me there's a way to do a "System Restore," bring up the "Command Prompt," or do "Startup Repair" without being an administrator. Those are the three options that require me being an Administrator. I've never had a System Restore fail before and can't believe it did. :-(

Hi SixSigmaGuy, If you were able to do a system restore it should let you do a refresh or reset and "yes" it looks like that will be your only 2 options and at this point if you have everything back up i will go ahead and do a reset to factory default.

My screen/apps keep refreshing?

I'll be watching a movie or a lecture in full screen and I'll be snapped back to iTunes without being able to see the show or I'll be working in one app and everything refreshes and suddenly I'm in a different app. This happens every two minutes or so.

This problem is often caused by "Google Drive." If it's installed, I suggest you first check for an update. If that doesn't solve the problem, remove it according to the developer's instructions. You may need to boot in safe mode to do so. Back up all data before making any changes.
If you use Google Drive and don't want to remove it, then try deselecting the option in its preferences to "show status icons." According to reports, that may be enough to stop the Finder from crashing.
