[SOLVED] Dual monitor: can't switch from X to vc

I have a dual monitor configuration on my laptop (Sony Vaio VGN-SR21M), so that I can work with the laptop screen and an external lcd at the same time. It works amazingly well, every screen has its own resolution and I can drag windows from one screen to another (ATI drivers are wonderful in this aspect!). The only problem is that I can't switch to vc pressing Ctrl+Alt+F2 or any other function key: the laptop screen freezes black, while the other shows "no input" box. Pressing Alt+F7 the X interface is restored correctly to both screens. If I start X without the external lcd the problem disappears, so I think it is a multimonitor issue. Here's my xorg.conf:

I think it has something to do with the Screen sections, but I don't know exactly where the problem was (I changed many settings at once). Hope my new xorg.conf could be useful to someone with the same problem. Thanks everybody for the help.

HT201320 How can I switch from one email user to another?

How can I switch from one email account to another?

You have to select between the two accounts in the mail app.
Say for instance that you are reading an email in your XYZ email account. Tap the button in the upper left corner of the mail app to back out all the way to where you can see all of the email accounts.... Tap InBox, then tap XYZ email Account and that will take you back to the main MailBoxes window.
Is that what you want to know? There is no way to simply "toggle" between the two accounts.

Can not switch from organizer mode to editor mode in adobe premiere elements 12.

After successfully installing and registering my new adobe premiere elements 12 and had created the organizer, I still can't switch from organizer mode to editor mode to edit a file (photo).

Alfredo Agorilla
What computer operating system is your Premiere Elements 12 running on? Have you updated 12 to 12.1 Update via a project's Help Menu/Update? If not, please do so.
You wrote
I still can't switch from organizer mode to editor mode to edit a file (photo).
Just how are you trying to do that...
a. Are you in the Elements Organizer 12 workspace, right clicking the photo's thumbnail, and selecting Edit with Premiere Elements Editor
or
b. Something else.
Is there an error message that results when you try to switch "from organizer mode to editor mode" and cannot?
When you mention "....to edit a file (photo)", I wonder if you are not trying to get to Photoshop Elements 12 Editor, not Premiere Elements 12 Editor, from the Elements Organizer 12.
Please supply a step by step of what you are doing so that we can be sure that we are in sync on the details that we are using to work through your issue.

With different dual monitors can you choose which image to print

I have dual monitors which I calibrate but they still look different. I have lightroom on the main screen with a full loupe view on monitor 2, I would like to print this image (on monitor 2 ) as its easier to see the changes during develop because its bigger. Is this possible or does lightroom only print the image either on the main screen or in the main lightroom module

You are only previewing through the monitor profile. It does nothing else in the chain to Print. There's no conversion done between monitor profiles and printer profile, just Lightroom's internal working profile and the printer profile. Photoshop converts between the working profile and the printer profile, again the monitor profile is only applied to what you see on the screen. The actual process of colour matching can never be 100% exact, but can get close under ideal viewing conditions. The screen emits light, whereas the print must be lit, and takes on the colour of the light in the environment. High end printers will viewing stations with with which to determine print accuracy.. a luxury most of us won't.
In more simpler terms, make the print. Compare it to the monitors under good daylight and gauge from there which is closest to the print.

[SOLVED] Dual monitor acting weird on Fluxbox after system upgrade

Hello.
I'm using Fluxbox on Xorg. I have two monitors and for more than one year my setup has been this in ~/.xinitrc:
#!/bin/sh
if [ -d /etc/X11/xinit/xinitrc.d ]; then
for f in /etc/X11/xinit/xinitrc.d/*; do
[ -x "$f" ] && . "$f"
done
unset f
fi
xrandr --output DVI-0 --mode 1920x1080 --pos 0x0 --output DVI-1 --mode 1680x1050 --pos 1920x0
exec startfluxbox
Now, I just upgraded my packages (fluxbox and some xorg-* packages were upgraded, like xorg-server, as well as xf86-video-ati) and, although the dual monitor setup works, it seems like each monitor is not recognized individually. My Fluxbox toolbar spans on both monitors horizontally (whereas it used to reside on the left one) and when I maximize a window, it's maximized on both monitors (whereas it used to be maximized on one monitor only, the closest).
Before reverting the upgrade, anybody knows why this is happening?
Thanks,
Phil

Yup, I can confirm that. It's the fluxbox package.

[SOLVED] Dual monitors and raid - linux newb

Hi
I'm raginaot and I'll probably be asking a lot of dumb questions here in the near future
I just decided to say goodbye to windows for a while. Been wasting too much time gaming and it was either - switch to linux or - sell my computer and move to the desert. I'm gonna try the former first and see how it goes.
I managed to install arch and get gnome up and running with the help of the most awesome linux install guide I have ever seen and I installed the xf86-video-ati driver package but I'm having trouble getting it to recognise my 2 monitors.
I'll list my hardware specs before I go any further:
CPU: i7 920
RAM: 12GB (3x4) Mushkin Silverline 1333MHz
Motherboard: Gigabyte EX58-UD3R (rev 1.6)
GPU: ATI HD5870 1GB
Souncard: Auzentech X-fi forte
Monitors: Samsung 2693HM and Samsung 226BW
now the monitors seem to be stuck in mirrored mode, both showing the same image at 1280*1024 resolution
when I try to set them both to on and their native resolutions (1920*1200 and 1680*1050) in the display settings I get a message that says:
"the selected configuration for displays could not be applied
required virtual size does not fit available size: requested=(3600, 1200), minimum=(320, 200), maximum=(1920, 1920"
But when I unplug the 22" display, I can set the 26" to native res just fine and vice versa.
Now to the second issue...
I have 2 1TB drives in raid0, but in fdisk -l they appear as 2 seperate 1TB drives instead of 1 big 2TB like they're supposed to (see output below).
I guess I have to mount them in some special way, but I have no idea how. The raid worked right away in linux mint.

Glad you were able to figure out the RAID part - I can't really help you with that. As far as the dual monitor setup, I would suspect that you will need to do some stuff with the xorg config to get it working. I would say that xorg.log would be the first thing to look at - to see what is limiting the modes available to X. Maybe post the xorg.log and your x configuration
My post in this thread might give a bit of background on how X comes up with what resolutions it lets you choose.

Not sure what to look for here...
The "#DisplaySize 470 300" line looks like something.
I only have the 26" screen plugged in at the moment, if that matters. Does the xorg log change it self when I plug in another screen?

You can add as many e-mail accounts as you want. Go to Settings>Mail, Contacts,Calendars to add them.
When in the mail app,you can have all inboxes displayed together (unified inbox) or you can tap the "Mailboxes" arrow in the upper left and select which one you want.

Dual monitor setup experiences noise from sleep wake

I have a second monitor hooked up to my 27" iMac and it will experience noise when I wake my computer up from sleep periodically. I have reformatted my computer twice now for other reasons, but the problem still continues. I have to turn my second monitor off and then turn it back on again and it will work great. It is just really annoying to wake my computer from sleep and only one monitor is running, but the computer still thinks the other monitor is connected, windows that were still running are still on the other display till a turn off the second display or click gather windows from the display setting in OS X.
The noise on the second monitor looks like an old tv when you are not on a channel that has reception. Its like a bunch of black and white dots flashing around. We used to call them ants in the tv when I was younger.
Any help out there?

Jared Blake:
I have the same problem, I think.
I used an external monitor with my previous iMac, no problem. In the past month or so I bought a new quad-core 27 inch iMac, and moved the external display to the new machine. Everything works normally, except that when I wake up the system, the external ViewSonic display is filled with "snow". Cycling power on the external monitor always restores it to correct operation.
The "snow" pattern looks very much like the old days of analog TV, before empty-channel "blanking" was developed and added. In essence, the TV was displaying random information.
This is the only case I can recall of seeing "snow" on a modern (i.e. digital monitor.) As far as I know modern monitors can detect that no valid signal is coming in, and in such cases, they display a blank screen and possibly a message saying something like, "no signal".
So, I'm guessing that our iMacs for some reason are not detecting the second display on wake-up and are not sending any signal to it.
It's strange that the monitor's themselves don't react better to this situation.

Can you switch from a mobile site to a full site through iOS not the website??

Hi,
Is there a way to switch from a mobile website to a full site through iOS not the website becase the particular MOBILE website I am on does not offer the option to switch to full website??
Thankyou.
Kind Regards

Not with Safari. There are some browsers available from the App store that have that feature. I think iCab is one.

Can I switch from the full creative cloud package to just photoshop and illustrator.

Can't Switch From AOL To Apple Account

In preparation for a new phone on June 29th, I'm trying to switch from AOL account to Apple account. I want to be able to migrate all my TV show purchases to my new phone.
I enter the incorrect AOL password a few times, then iTunes lets me enter account information to change the account. It looks like it gets hung up on the final (or nearly final) step, where iTunes asks what county I live in for tax purposes. I choose my county, click on "Done", then the following red text appears... "We are currently experiencing technical difficulties. Please try again later."
Well, I've tried this again "later", entering the text several d*mn times (I'm getting VERY frustrated at this stage) over the past several days! I need to get this resolved immediately!
Help!

[Solved]Dual Monitor Setup

So, I inherited a new monitor from my friend just a couple days ago and had a go at setting it up. Here's my current setup, to illustrate:
-- MOD EDIT -- Please follow image posting rules
The one on the right is mirroring the left at the moment, which happened via default when I booted up. I have the monitor to the left plugged via a dvi cable, and the one to the right that is rotated (for the purpose of better viewing webpages) with plain old vga. Both are running off my only graphics card, a Radeon X300:
$ lspci | grep VGA
01:00.0 VGA compatible controller: ATI Technologies Inc RV370 5B60 [Radeon X300 (PCIE)]
Here is the compatible resolutions and refresh rates and such for each:
$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 4096 x 4096
VGA-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm x 301mm
1280x1024 60.0*+ 75.0
1152x864 75.0
1024x768 75.1 60.0
800x600 75.0 60.3
640x480 75.0 60.0
720x400 70.1
DVI-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 450mm x 280mm
1680x1050 60.0 +
1280x1024 75.0 60.0*
1440x900 75.0 59.9
1152x864 75.0 70.0 60.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 72.8 75.0 66.7 60.0
720x400 70.1
S-video disconnected (normal left inverted right x axis y axis)
So, this information aside, I went and tried to add my second screen and make everything happy, I used the dual screen section in the X.Org Wiki page, which I believe was for the nVidia users, but I couldn't find any direction otherwise, so I figured with a few changes it could work with my radeon just fine. I am on xorg-server 1.9.4.901-1 with openbox as my window manager, no complete DE.
This is my current /etc/X11/xorg.conf.d/10-monitor.conf written for two monitors, which at the moment does not work, saying no screens found when I run startx:
Section "ServerLayout"
Identifier "DualScreen"
Screen 0 "Screen0"
Scren 1 "Screen1" RightOf "Screen0" #Screen1 is to the right of Screen0
Option "Xinerama" "1" #To move windows between screens, set to 1
EndScetion
Section "Monitor"
Identifier "Monitor0"
Option "Enable" "true"
EndSection
Section "Monitor"
Identifier "Monitor0"
Option "Enable" "true"
EndSection
Section "Device"
Identifier "Device0"
Driver "radeon"
Screen 0
EndSection
Section "Device"
Identifier "Device1"
Driver "radeon"
Screen 1
EndSection
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "TwinView" "0" #Set to 1 to make both monitors act as one big screen, with no distinction between the two
SubSection "Display"
Depth 24
Modes "1680x1050_60.00"
EndSubSection
EndSection
Section "Screen"
Identifier "Screen1"
Device "Device1"
Monitor" "Monitor1"
DefaultDepth 24
Option "TwinView" "0"
SubSection "Display"
Depth 24
Modes 1280x1024_75.00
EndSubSection
EndSection
And here is the same file, in a working configuration:
Section "Monitor"
Identifier "Monitor0"
EndSection
Section "Device"
Identifier "Device0"
Driver "radeon" #Driver used for this monitor
EndSection
Section "Screen"
Identifier "Screen0" #Collapse Monitor and Device section to Screen section
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24 #Choose the Depth (16 || 24) (24 for true colour)
Subsection "Display"
Depth 24
Modes "1680x1050_75.00" #Choose the resolution
EndSubSection
EndSection
This leaves me with 3 questions I cannot seem to figure out:
1) What did I do wrong with the non-working xorg config file, giving the error "no screens found"?
2) Another extra twist of difficulty comes from the rotated monitor on the right. How should I adopt for that, with resolutions and such?
3) Xinerama/Twinview - I am confused which one of these I should choose, what they offer over the other, or should I just not bother at all?
I would like, in a "perfectly good configuration", windows to be able to move from each monitor to the other, the monitors to be two distinct monitors (ie. they don't mirror each other), a maximized window to only fill up just the one monitor (and not both), and finally, fullscreen programs (like games and such) only fullscreen to the monitor they are on. Is such a configuration possible with all of these parameters?

Your desired configuration is quite common, and indeed, is the default setup provided by Openbox---once the monitors are properly configured, of course :-)
Anywho, modifying xorg.conf files for something like this is a thing of the past, man. (Incidentally, you have made the lethal mistake of assuming an nvidia config will work with an ATI card. For example, "TwinView" is only available when you are using the nvidia proprietary driver.)
Judging by your use of "radeon" as your video driver, it looks like you're using xf86-video-ati. Therefore, congratulations, xrandr will rescue you :-) (This should also be the case if you you're using the Catalyst driver.)
thinkwiki should be enough to get your feet wet. Note: This guide is a bit dated, but 90% of it is still relevant and useful. For example, it claims that you need to modify your xorg.conf to add a Virtual screen size---this is only true if kernel modesetting is disabled. If it's enabled (and it should be if you're using xf86-video-ati), then you're good to go. If you're using Catalyst, you will have had to disable KMS. So you'd either have to add a Virtual screen to use xrandr, or configure your monitor setup with amdcccle.
Finally, you asked about rotation. I don't think this is anything that `man xrandr` can't answer, and you should be okay as far as support goes---rotation was added in RandR 1.2, which any civilized video driver should support. (Except nvidia blob.)
Anywho, feel free to come back with more questions if you have any!
(For terminology sake, this means you will be using neither Xinerama nor TwinView to configure your multi-monitors. You will be using RandR if you use xrandr. Interestingly, your screen setup will still be reported to Openbox via the Xinerama extension. You may be interested in a utility like `lxrandr` if the command line frightens you.)
Xrandr does the job elegantly, thanks! It's a simple matter of putting the commands I needed in openbox's autostart.sh. Thanks for pointing me in the right direction.
#xrandr --output DVI-0 1680x1050 --output VGA-0 1280x1024 --right-of DVI-0
# xrandr --output VGA-0 --rotate left
