Disable half of screen with xrandr

I have a large monitor that was damaged some time ago, and I can only use half the screen. To make things easier for me, I'd like to use xrandr to disable that half, and make it seem like I just have a single monitor at half the size of the old one. I'm able to successfully constrain my mouse to half of the screen if I use xrandr --fb option. This also makes the other half of the screen black, but my windows still seem to extend all the way to the bottom. In other words, they extend into the black half of the screen.
Any suggestions?

That new resolution is probably going to still fill the whole screen via stretching, just like what happens with non native resolutions, but it doesn't hurt to try.
At least here limiting the size with --fb only works vertically, maybe you can try rotating the screen and see if using --fb to limit the size vertically works.

Is there any way to disable the lock screen with out the screen staying on?

I know there is away to disable the pass lock but is there a way to disable the screen from locking every time the screen goes off? cause it's so much easier to just press the answer button than to slide it to unlock. phone versions iPhone 4s and iPhone 5c.

You're confusing a direct answer with a rude one. Wjosten's reply wasn't rude. It was accurate and direct, without any sugercoating. You can't get the device to operate the way that you want (lock the screen, but not really 'lock' the screen). It's not a 'screensaver' like on your computer. It's a lock screen, designed to prevent accidental activation of the device screen, and possibly launching apps, making phone calls, etcetera.
If you want an option added that allows the device to do what you want, tell Apple.

Unable to switch back to laptop screen with xrandr from VGA

HI,
I'm using i3 window manager and have an external display plugged in sometimes. I use the following short script to turn off the laptop display and turn on the vga monitor
xrandr --output VGA1 --auto
xrandr --output LVDS1 --off
xrandr --output VGA1 --auto
feh --bg-fill /home/james/wallpaper.jpg
synergyc 192.168.0.4
However I cant get back to the laptop screen turning the VGA off doing it the other way round.
xrandr --output LVDS1 --auto
sleep 2
xrandr --output VGA1 --off
sleep 2
xrandr --output LVDS1 --auto
sleep 2
feh --bg-fill /home/james/wallpaper.jpg
pkill synergyc
I've tried using --mode 1366x768 but that doesnt work. The only thing I can do is close the laptop lid and then resume from suspend and the screen comes back on.
Anyone know what I can do to get my laptop screen back on?
Thanks.

Try the whole thing together
xrandr --output LVDS1 --auto --output VGA1 --auto --right-of/left-of/above/below LVDS1.
If you have it plugged in, it runs both, if you unplug it only brings the one back on.

March Win Update Disabled All Touch Screens, Wifi and BT? WHY?

I give up - everything I have done, this is a brand new Dell Inspiron - both images are shown below, one from Registry Editor - showing proof of the Mainboard's date and the BIOS. I run on a Touch Screen, Win 8.1 Pro - I had exhausted everything in the world;
even Microsoft Tech Support in Tier 3 can't figure this out - it was working fine all along, but come late February; MSFT comes with these new Windows Updates and making it worse March wipes out literally the BT (Bluetooth), turning off completely the WiFi
(although all are enabled in Services) and considering this is one expensive piece of equipment here ... C'mon now... All my Firmware and everything else is up to date and up to par and was working peachy until Intel came up with their update of the Intel
i5 Core (see below in Device Manager - you will see where Microsoft Windows and which KB is it - I am clueless now, because the info is vague and I've had to wipe out the entire HDD and reinstall it via the OEM DVD Win 8.1 and redo the whole reinstallation
all over again) and you are installing via Windows Update i7 Series and this is not an i7 Processor - there are no i7 series for i7 Core Processors - I am sorry... Intel does not have this. Then with Bluetooth; I give up - I have it all (hidden) uninstalled
and wiped out literally; superimposed for security reasons because for the life of me I have no earthly idea where to even start anymore, neither does Microsoft Tier 3 either.... they are clueless too! Now you've disabled my Touch Screen with your March
Updates where this now is completely a DESKTOP and it is not designed for mouse usage; it is designed for swipe or touch and go ... self sufficient are the images posted below for you to see and figure this one out yourselves.... I've done everything possible!
Yes, everything is there and functional once everything is reinstalled but once that Windows Update begins - that is where the problem begins, I have the Windows Update on MANUAL Mode so I can view the KB's but sadly, many of the KB's are very vague in information;
this is not helping me here - before I know it; I am right back to square one! Since this will only limit me to two images - so the best I can provide you is that of BIOS and Device Manager to show what mess the Windows Update is giving everyone who has touch
screens (RT - Ultrabook to Surfaces) a massive headache; you cannot turn it on, if it were possible - I could show you also how these are enabled in Services.
PS: NOTE - the Service Tag has been Blacked Out to prevent theft - there are no information there that people can steal from in BIOS and the other from Device Manager (followed by the BIOS first) ... go and figure these out yourselves... I am throwing in
the towel; it has nothing to do with the Manufacturer - everything was working just fine; but I can't disable Windows Update because I need it! See the point - it is futile and vain!
"Vujà Dé - The feeling you've never been in here before"

Understand your frustration there, but let me try to help
May I know your detail Dell Inspiron model?
What I suspected is, Dell launched the newest update for your Chipset, Bluetooth, WIFI and Touchscreen driver or software. Since you perform Windows update, OS will obtain latest driver via Windows update. Maybe incompatible driver which comes from
Windows update didn't match with your PC OEM hardware, that the reason why processor information, Bluetooth, WIFI and touchscreen don't functioning normally even worse will they turn grayed out or disable.
What I suggest here you check at Dell site, maybe there is update driver for this specific Dell model. Or let me try to find it for you. You can also download manually from there and applied the update
And maybe incomplete or corrupted Windows update process and downloaded files will caused issues like this

Satellite A305-S6898 - half black screen on the start-up

I purchased this laptop back in the beginning of March and had to return it to store due to an issue at start-up when half the screen would turn black on the Windows log in screen. They ordered me a new one that I received about 3 weeks ago and I used it for about a week before I got the same issue of half black screen with the start-up.
Now it has been running really slow and about an hour ago I had it freeze up on me and my entire screen turn into a bunch of colorful lines.
I had to restart into safe-mode and run a virus scan just to make sure that wasn't my problem.
I don't download anything on this computer other than the basic messengers and photo editing programs.
I have an HP MP7170N desktop which i use to download everything that seems to run quicker than the laptop and I use photo programs, downloads torrents and store most of my music and photos on that one and it only has 1GB of memory compared to this ones 4GB.
What is the deal?
Anyone have any ideas as to what I can do.
I can't really return it to the store because they only give a 14-day grace period for returns.

Looks not good for me it sounds a little bit like graphic issue.
Before you would contact a professional Toshiba authorized service provider it would be interesting to know if you would notice some improvements after recovery procedure and BIOS update.
I believe you didnt get an recovery disk because you can create it using the preinstalled Toshiba software check your user manual how to create recovery disk
So after new installation check the notebook usability and if similar issues still persists.
If nothing will be changed its strongly recommended to contact an ASP

Did you try to use recovery mode, explained in this article?

Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.

If recovery mode does not work try DFU mode.

After screen replacement, top half of screen starts by looking normal but then fades to black while bottom half stays bright but with images blury. What might went wrong?

A friend recently gave me their old Macbook pro 15 because they broke the screen and the Apple store quoted them $500-600 to fix it. I looked online and bought a screen of ebay for $170 in hopes of fixing it myself. After getting the screen I hooked it up using the steps I found online. Sadly when I turned it on, the top half of the screen was working apparently normally, but then it faded to black. The bottom half stayed bright with color the whole time but the images were always blurred. When I close the screen with it on, then open it after turning the computer on, the top half lights up with my desktop images as if it is working fine but then fades to black. The bottom is still blurred the whole time. What all could be wrong? Display cable, Inverter cable, not registering the screen or something, the screen is bad? I don't now a ton about all this and I have learned most of what I know from online research. I am not sure if I should send the screen back or if there is another issue. I just want to fix this thing.

Unfortunately, you don't even know the lower half of the computer is working properly, because you didn't have it until after it had been abused. So forget the attached screen for the moment. Connect an external monitor to it, fire it up, and see whether you can get a usable image on the external screen. If you can, send the defective "new" screen back for a refund, or replace the LVDS video cable first to make sure that's not where the problem lies, and if it isn't, then resort to sending the screen back. If you can't get a good image on the external, give the junk machine back to your friend and walk away.

I do hope you have recent backup, because it look like your hard disk is failing. You can start up in Recovery Mode, and run Disk Utility to see if the disk can be fixed: OS X: About OS X Recovery - Apple Support

My IPad has one half of the screen with vertical multi colored stripes and the other half is normal. Has anyone had this problem and if so is there a solution?

You could have a hardware issue, but try this and see if it helps.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

I walked into a dark room with my iPad and tripped on something. I then dropped the iPad on my bed. When I fell my elbow landed right in the middle of the screen of the iPad. I have a 30 dollar case. Now half the screen is black. What should I do?

Not much you can do other than to take or send your iPad to Apple and pay their replacement charge.
Regards.
