[SOLVED] KF5/Plasma won't start without external monitor

I have connected an external monitor through HDMI, it works fine in plasma5, the only problem is, if HDMI isn't connected I can't start Plasma 5. I just attached the monitor again, disabled it in the setting (the monitor stopped showing any display, but now Plasma gives black screen if HDMI is not connected, but if HDMI cable is connected the laptop screen would turn on just fine.
I have tried removing the kwinrc and all plasma* from ~/.config but to no avail.
How can I reset it?
P.S: I created a new 'test' user, and Plasma works fine with it, so it's not an installation problem but a configuration problem.

Ya, I run dual monitors on a single nvidia card and on about every second or third reboot, I would end up loging into mirrored screen 1. I would have to disable compositing, reset screens in nvidia-settings, then re-enable compositing. Someone else was complaining about the artifacting and said he cured it by removing those two applications. I figured I could skip the disable and enable of compositing and was pleasantly surprised to find that it also cured the mirrored screen issue too.

IMac won't start without install disc

Hi, I'm new to all of this. I tried resetting my admin password using install disc on my iMac as I'd forgotten it. Now iMac won't start without disc. If disc is ejected on restart apple logo flashes between no entry sign and folder with "?" on it. Will start up with install disc in, but then wants me to choose language and install OS. Tried repairing and verifying HD and all seems ok. Tried holding option key and selecting HD on startup, but same outcome - choose language and install OS. How do I get back to normal desk top? Do I have to install OS again? Will I lose data? Please, please help! Thanks.

It should only take a minute or so at most to boot from the DVD.
If your sure you have the correct Install Disk for that iMac, I'd start over. Then if it still doesn't work then perhaps a trip to your Local Apple Service Provider with the Disk or Disk and iMac is in order.

Alternately using the correct Disk as per the following article, see if you can run the Apple Hardware Test? > http://support.apple.com/kb/HT1509

My mac won't recognize an external monitor. The screen Goes Blue Once, then goes blue again and the second monitor just turns off. I am using an HDMI adapter to a visio TV. I also have my xbox on the tv. Can anyone Help??

Lol, figured out the first part. Just for those who may be searching, when you click on the Display Preferences, and click on the arraingment tab... it not only shows where your two screens will be displayed, but the WHITE BAR at the top of one screen is the dock/toolbar. Click and hold to grab this and just slide it over to the screen you'd like it to be on.
You have to release it IN the screen box, not on top of it... and it should pop right over to the new (or old) screen. At any rate, you can put the dock on either (or any) screen that you prefer.
I am thinking of ordering more of these. Lol. 3 monitor setup seems like it would be crazy good.
Still looking for the answer to keeping the new 16" screen on the right without switching between screen #s with that... not expose... Lion feature.
Thanks. Hope my other question has an answer out here.

I have a PowerBook G4 with a non-functioning monitor. It used to work with an external monitor, but I reinstalled the OS, which cleared the display preferences and now when I restart it won't detect the external monitor. How do I fix?

I have a PowerBook G4 with a non-functioning monitor. It used to work with an external monitor, but I reinstalled the OS, which cleared the display preferences and now when I restart it won't detect the external monitor. This means I can't use the computer anymore. How do I fix? I tried using the Command+F2 keyboard shortcut, but it doesnt' work. It's possible that since I reinstalled the OS, it still needs to be set up, so there's only a welcome screen (but since I can't see it I'm not sure).

There is no limit to the number of times you can re-install Office on the same computer.

New iMac won't recognize my external monitor.

I just upgraded my workplace computer to a late-2012 iMac (with the thin edges) from the previous older model.
I have an external monitor that I use as a secondary screen - a Samsung SyncMaster BX2440 - that worked great on my older machine using the DVI adapter.
When I plug the same adapter into my newer machine, it won't recongize the external monitor.
I tried resetting the PRAM, but no dice.
Is this a Thunderbolt issue, and if so, how easy is it to resolve? Do I just need to get a newer DVI adapter?

Loner: I looked at that and it only shows the main iMac display. Doesn't show the other device.
The model I'm using is a Thunderbolt machine (has the lightning bolt arrow icon). The previous machine was a DisplayPort model.
The adapter is the Apple-issued DVI adapter, but I'm guessing that even though TB and DP use the same physical plug interface, the adapters are not compatible?
(The adapter has the standard monitor icons on it - box with vertical lines on either side).

Why won't Macbook Pro startup properly without external monitor & keyboard?

If I connect a external monitor and keyboard to my late 2011 Macbook Pro (running Lion) it starts up just fine.
But if I try to start it up without these (or any other devices) attached, I get no display on the internal screen and the internal keyboard is ignored (the caps lock light doesn't light up when the key is pressed).
However, I don't think it's a hardware issue, as a PRAM reset seems to work (I get the second chime) indicating that the keyboard is OK. And I get a second or so of grey screen before the screen goes black.
I've tried resetting my SMC and my PRAM. The latter seemed to fix the problem once - but then it came back, and won't go away again this time.
I've also tried starting in safe, single user, and verbose mode, but none of these seem to make any difference.
I've been having some issues installing Windows (under both BootCamp and Parallels) but wouldn't have thought that these were related.

I have solved my own issue, so wanted to post here in case anyone else encounters the same thing.
My Macbook was less than 90 days old, so I booked a telephone support call from Apple. But they couldn't help. So I booked a genius bar appointment. I turned up, powered up my Macbook, and it worked fine!
Since it was working OK, there was nothing for them to investigate (though they ran some basic diagnostics anyway). But as soon as I got home it stopped working again.
Now this was really weird, so I started eliminate anything that was different between the environments - power supply, cooling pad, laptop stand...
My Macbook normally sits on an aluminium cooling pad, which in turns sits on a steel laptop stand. And when sitting on both of these (or just the stand) it exhibited the behaviour above. However, when I put it on a wooden desk it worked fine! So I replaced the aluminium cooler with a gel pad and it still worked fine. But why...?
I also noticed another difference. Once I reconnected an external display and keyboard, I found that my internal display now stayed on - whereas previously it had gone off (with only the external display staying on).
Searching on the internet, I discovered that this was normal behaviour under Lion, and what I had experienced previously was abnormal behaviour when the lid is open - but normal behaviour when the lid is closed. And since Macbooks use magnets to determine whether or not the lid is open, those who preferred the closed lid behaviour were using fridge magnets to fool their Macbooks into behaving that way.
It seems that my stand and/or cooler was acting in the same way as a magnet, and making my Macbook think that the lid was closed. So the internal display stayed off whether or not I had an external display connected. Isolating it from the stand with a gel pad has resolved this issue.
So I guess that Macbooks weren't designed to be used on metal surfaces...

[solved] xorg proglem - won't start, but no error

Hi folks!
I'm new to Arch, my first installation, but I used to use Gentoo in the past. Got a problem with making X to run. I followed the guide from the wiki, but I didn't manage it to work.
I'm using nVidia drivers from 173xx branch (GF 5900XT). Hal is working properly, I hope - /etc/rc.d/restart successes w\o errors.
At first, I tried to run X without xorg.conf and it complained about missing 'nv' and 'vesa' (i hope) modules. Then, after running nvidia-configure (/etc/X11/xorg.conf was successfully created) and startx - screen blanks (no nVidia logo shown) and after ~3 seconds it comes back with massage "waiting for X server to shut down". In /var/log/Xorg.0.log there were no lines starting with (EE).
Then I tried to configure X with "X -configure". After making new config and replacing the older one at /etc/X11/xorg.conf and running X with command startx (as user), it complained about missing type1 and truetype modules ((EE) lines as far as I remember). After installing missing packages/modules:
http://dpaste.com/60888/
it still won't start. Screen blanks, no nVidia logo shown, and later comes back with well known screen ( usual text... look over /var/log/Xorg.0.log for more details...). Only message after default text id "waiting for X server to shut down", with no (WW) nor (EE) lines above.
More useful data comes:
Xorg.0.log
http://dpaste.com/60883/
xorg.conf
http://dpaste.com/60885/
tail of dmesg
http://dpaste.com/60887/
If you need anything else to see, request!
Any idea? To me, it looks like nvidia driver bug or some xorg bug (or maybe just a misconfiguration)
In ~/.xinitrc stays only "exec startfluxbox", but even with empty file, situation is the same.
Thank you in advance,
Daniel

Hello, welcome to Arch!
You should read about the new feature of Xorg, input hotplugging: http://wiki.archlinux.org/index.php/Beg … otplugging
A more detailed explanation can be found here: http://wiki.archlinux.org/index.php/Xor … otplugging
Be sure to copy the fdi file in the correct directory.
Since I am using also the 173xx branch, here is my xorg.conf, hope it will be useful for you:
http://dpaste.com/60927/
EDIT: Not 100% sure but I seem to recall that the nvidia driver has some problems when you don't set the default depth. Add that line

[SOLVED] GDM/Gnome won't start after update

Today after I run pacman -Suy, GDM/Gnome won't start anymore after reboot. The error message I get after GDM starts is:
Oh no! Something has gone wrong.
A problem has occurred and the system can't recover. Please contact a system administrator
Does anyone have any idea what happened and how can I recover the system?
Here is the complete log for the update:

Here is the journalctl -u gdm log:

And here is the /var/log/Xorg.0.log:

I can't imagine any other log file that might help figure out what happened, let me know if there's anything else.
Any help is appreciated. Thanks.
Edit: I stopped gdm, created a ~/.xinitrc and could successfully start Gnome with startx. The problem remains with GDM.

I'm not sure my issue is really the same one, but am hoping for some guidance here if possible. Trying to start GDM gives me the same error message/screen. After tdm fails I can switch to a console,
sudo systemctl stop gdm.service
then
sudo systemctl start lightdm.service
and lightdm starts fine. However, trying to log in to gnome-session gives me the very same error as I had with GDM. I can log into XFCE just fine. Attempting to start gnome-ession via startx also gives me the error screen. Does anyone know how I can diagnose the problem? Thanks,
Matt

My laptop won't start without battery mounted

Hello! I have a Compaq CQ61-200sq laptop and recently my battery just got "old". So for the time untill i will buy a new one a just took it out and try to use the laptop without battery, just with the AC adaptor pluged in. But, just i said it won't start if i don't mount the battery. If i took the battery out while it's on there is no problem.
So, my question, beside what could be the problem, is if the problem will disapear with a new battery. I don't want to buy a new battery and still have problems.
Thank you!

I updated it about two to three times and would still experience the same problem.
Why update 3 times?!? If you run an update, and it installs normally, that it - done!
There's a world of difference between running BatteryUpdate 1.2 and installing a new battery. In fact, if you read the linked page above, it states that the after you run battery update if you experience any of the listed problems you should contact AppleCare. Their first step will be to replace the battery. Could it be a logic board problem? Sure. Is that the first thing they'll do? No. By that reasoning, the first thing to try if your car fails to start on a cold morning is to put in a new engine...
So, to the OP, contact Apple - or better yet, if it's convenient, go in to an Apple Store. Get a new battery. If the problem persists, go from there. The advantage of taking it into a Store is that they'll test it on the spot.

Macbook Pro - Applications wont start without External Display

Hi all,
Apologies if this question has already been answered, but I have spent a lot of time Googling to no avail...
I have an early 2011 15" MBP with the following spec:
Model Name:          MacBook Pro
Model Identifier:          MacBookPro8,2
Processor Name:          Intel Core i7
Processor Speed:          2 GHz
Number of Processors:          1
Total Number of Cores:          4
L2 Cache (per Core):          256 KB
L3 Cache:          6 MB
Memory:          8 GB
Boot ROM Version:          MBP81.0047.B24
SMC Version (system):          1.69f1
AMD Radeon HD 6490M / Intel HD Graphics 3000
Snow Leopard Mac OS X 10.6.8
I normally use the MBP with a 27" Cinema Display connected (mini display port/thunderbolt connector) and the clamshell shut. All is fine.
However, if I remove the external monitor and want to use the MBP with just its own display, some applications will not start. They bounce int he dock for a while and then hang, and need to be forcibly killed. Not all applications behave this way, but so far I have experienced this with Aperture 3.2, Omnigraffle, Parallels, Pixelmator.
Does anyonw have a clue whats going on and how to fix?
Thanks

Hi Grant & Bob
Thanks for your responses.
The adaptor has been removed from the Mac, and I have tried all the obvious solutions (like using detect displays), but to no avail.
I will try and investigate some other scenarious (like using a different external display) and see what happens.
Thanks

Yosemite Won't Shutdown With External Monitor Connected

Hi there...
I have a MBP 2010 and I've updated Yosemite from Mavericks. Now I'm running the latest 10.10.2.
Ever since I updated to Yosemite, I have had this problem of my computer won't shutdown when an External monitor is connected. This happens only when I put my computer to sleep.However, if I restart the computer and after logged in to the user and tried to shutdown, it shutdown without any problem. Every time I shutdown it just hangs and I had to force shutdown by press and hold the power button. Which I'm sure is not a proper way.
Right now only my external monitor connected to my MBP. So I did unplugged the ext. monitor and tried shutdown and it works fine. But it think this is the temporary solution that I've found but it is annoying to unplug everytime I wanted to shutdown and plug it back in once the computer is up and running. Which is not idle solution at all.
Am I the only one or a lot of people facing this issue? If there is a solution please share. Very much appreciated. Thanks.

Updated to 10.10.3 and the problem still persist. Still unable to shutdown or restart after wake up from sleep.
Any one affected? Is it something to do with Gfx card?

Sounds like it's still not working??
Try a re-setup and re-start. Shut it all down and re-connect from scratch.
