Scaling Issue - Linux

I recently, after not solving my boot issues, reinstalled Manjaro on my Linux HDD. I have 2 Samsung 4K Monitors that I've always scaled to 200% on Linux and Windows.
On my 2nd Monitor though, some apps like System Settings, Calculator and others won't scale up. Most of my stuff is fine.
Any fix for this?

I can't believe no one had a reply for this

Occasional Lag

Has anyone else had an occasional scrolling lag in situations? It's happened to be on the Program List where the Program icons don't load immediately. Also, most noticeably in apps such as Beezz the scrolling is laggy... Is it just me, or are others experiencing the same...?
Early bump as I'm trying to decide whether a Hard Reset is in order, maybe I installed something that didn't fare too well. Thanks guys.
80% (if not more) of the 3rd apps are NOT optimized (or rushed diplomatically saying) for Windows Phone 7 OS. HTC Hub for example wasn't as fast as the new update for it.
I can make a slight lag (more of a chopping than lag) ONLY IF I visit WPCentral page which chops on my browser than after 4-5 minutes it disappears. So I am pretty sure it's not optimised well rather than a lag because let's face it , the hardware is there and the OS is damn fast.
Have you also experienced start menu icons taking their sweet times to show up?
I've seen some choppiness on 3rd party apps. Agreed that it is a developer issue as they learn how to make apps for wp7. beezz is better than it was, but for best results, m.twitter.com is your best option.

In almost 1 month of use, never I have. To continue my initial post, that is one of the reason why I haven't installed many 3rd apps. Personally I hate having a sleek OS and then enter an app and feel like Android.. In fact besides YouTube and Adobe Reader I have only 4 other apps installed.
Same here. I can repeatedly reproduce the program list icon thing by scrolling to the bottom of the list, then hitting the home key, it'll fly to the top of the list and you'll see "white stars" before it switches to the home screen instead of the icons. Happens in random situations too, this is just a consistent occurrence..
I'd like to point out that as a developer, the choppy scrolling is a platform issue with the way Microsoft have design listbox scrolling - Silverlight defaults to virtualising the list box and recycling the listbox items - and this works fine of the PC where there is enough processing power to recycle and virtualise whilst you scroll. However, with Windows Phone 7's limited processing power, and Microsoft's very unoptimised seeming implementation, listboxes can't virtualise data fast enough. Ergo, voodoo is needed to get it working to scroll smoothly You could turn off virtualisation, but then that greatly increases RAM usage, which in Silverlight is already and lot, and then you get comparatively long load & draw & render times, and blargh. There's no one good way to do it yet for long lists - not until Microsoft go and optimise the Silverlight platform better.
I'm assuming the program list icon thing is to save RAM - you can also get it with the Home screen tiles if you have a lot of tiles on it - and saving RAM is something Windows Phone is going to like to do, seeing as the apps and the Silverlight platform use up so much RAM
i had my hd7 for almost a month now and experienced lag on it. there was also an instance that icons of the apps i installed via market place took a few seconds to load up. theres also this occasional slow response time of the unlock screen. i still have 9gb of space though

What is actually happening under the hood with WebTob 3.0 on a Lapdock?

So I am running the first ICS leak (6.7.2231) and I am loving it. I also love that webtop is much more usable out of the box then the original. Can anyone explain to me what is actually ahppening OS wise when I connect my phone to my lapdock?
I've noticed that I can have different wallpapers and some apps don't stay running (VPN and terminal that I've noticed).
I understand that the original webtop ran a custom debian (I think) Linux install when you connected it. Is it actually running a separate instance of Android when I connect it now?
From what I can deduce it automatically modifies the Android configuration files to set the tablet mode for higher resolutions and then restarts all the significant processes. It only seems to work with the stock launcher as well, has issues when used with Apex at least.

[Q] Reset in emulator and backup restore?

I have an actual WP8 device that I've backed up to skydrive (contacts and sms). I would like to be able to pull that down into the WP8 emulator which I have installed and running fine.
Am I correct in that you can only restore a WP8 from skydrive backup on the first cold boot after a reset?
When I try to reset the emulated phone via the Settings/About page, the emulated phone shuts down and restarts, but hangs when it restarts.
1. Is there a way to get the emulated phone to restore from skydrive without doing a full reset?
2. Is there a way to make the emulated phone do a full reset and bring up the initial first boot screens so I get the restore options?
Thank you.
The Emulator does not support setting a Microsoft-Account which also means that SkyDrive access, Backups or Marketplace Downloads don't work.
Well.. That's unfortunate.
No way to mount the flash and hack on a xml/etc file? Also, I was mistaken about the emulated phone hanging on restart after the reset. It does come back up after about 5 minutes. and I very briefly see some text on the screen right before the windows start screen, but it flashes by so quick I can't make it out. It looks like it may be the initial welcome information, and the emulator is automagically bypassing it?
The emulator can't do anything other than eating away at your resources and fool new developers into buying new hardware to support hyper V. The only useful thing you can do with them is check how the layout looks under different resolutions.
When you re/start it, you need to have the entire OS image do a complete OS boot. It takes so long because it is emulated (obviously, on a phone is a lot faster). It also uses different architectures (x86 compared to ARM on actual devices)
As I said, you can't do anything useful with it other than basic stuff like UI interaction and UI display.
Ehh I dunno about new hardware. Runs just fine on my i7 windows 7 gaming machine in a win8 vm in vmware
But yeah, completely ridiculous that it needs hyper-v and win8.
Hmm probably worthy of a different post, but do you know of a way to pull backed up sms from skydrive onto a PC?
As Long as you don't work with the Camera of NFC the Emulator actually works quite well. You can also simulate bad Network connectivity and so on which you can't do properly on the phone. The UI sometimes seems rather slow in the Emulator but actually it does outperform the phone quite a lot with CPU bound code (at least on my Core i7). Having Multitouch Support implemented in the Emulator is also a nice Addition.
I don't know of any way to Access the SkyDrive backup from anywhere but an actual device.

You forgot SD cards, media elements, any sort of audio playback, umm...well thats about it xD

Remote Access - Work Project

My boss had me setup some RPi 2's to access remotely and browse to download/route resumes from different sites.
Each machine has it's own login for a specific site (Indeed, Dice, Monster, etc.)
I removed a lot of the unnecessary packages and tried to slim it down. I tested out RDP, VNC and SSH. Some of my coworkers complain about it being laggy, especially Dice.
I have it setup right now for them using SSH and when they log in it opens up midori only. So there is no desktop environment running or anything like that.
It has seemed to help, but I was wondering if there was a way to maximize the performance, maybe tweak the kernel, or somehow give midori more memory to use when it runs.
If you guys have any suggestions that would be much appreciated. I'm trying to make it run as smooth as possible with little to know screen lag.
Thanks, very interesting!
I assume you are using the raspbian os. Run 'sudo nano /boot/config.txt' in a terminal to get into some extra system settings. (ctrl+x to exit) At or near the bottom, you should see something about #arm_freq. Here you can easily overclock your pi. I have set mine up to 1100Mhz(on the pi2). It's not perfect, I have had a few programs close unexpectedly, but it's hella fast. Play with these couple settings on one till you reach a stable, but still speedy system. Note -play at your own risk. You can potentially damage or break the pi this way, and your warranty WILL be void!
As far as memory goes, you can add swap memory.. Swap is a partition that is used as RAM when the RAM is full or close, and on a desktop it works great. But on a pi, the partition is written to the sd card. Modern sd cards are good, but they get bad sectors easily from repetitive read/write actions. Combine that with how often RAM has to read/write... it can significantly decrease the lifespan of your sdcard. Again, use at your own discretion. Swap is also slower than regular RAM, and many people recommend turning it off to lengthen sd card life
The biggest factor here I think though is ssh/vnc. It will take roughly twice as long as browsing on the pi (or a desktop) alone because the pi is acting as a relay; it has to get packets, interpret them, process and display (even if there is no direct monitor) then send them to the desktops to complete the same process.
cool share. Thank you!!

Linux and real time

Yes, I know there are some distributions that support real time, but I want to come at this issue from a different angle. If you are not familiar with low levels of the Linux OS, please do NOT speculate ! If you are familiar and I am talking crazy, just say so !!
Back in the early 70s, there was a "load and go" OS for PDP-11 computers called RT-11. It was very simple. While you could develop real time "embedded" applications on the target machine, DEC wanted you you to buy a second system for development. The application was transferred to the target machine via paper tape or some other slow simple mechanism (DECtape ?). The target was rebooted into the now load application and off it went. Crude but effective. Thousand and thousand of system were built around this hardware and software.
Time went on and eventually another "layer" was add on top of RT-11 ( developed by S&H Computing) called TSX-11. It allowed the target application to run in the "foreground" while having a "background" for an interactive user to develop the application.
So here is my question
Seeing as most SOCs have 4 or more processors, is it possible for Linux to only use 3 of them ? The 4th processor would run the application in real time (foreground), implying it would have to handle interrupts for those devices it controled. Linux would be running in the "background" and handling all of the "standard" IO. Linux would talk to the foreground via shared memory (pipe).
The big challenges would be loading the foreground application, starting and stopping it.
