I have already posted an entry somewhere on this blog on how to disable your touch pad if you plug in a usb mouse. But I've just found out that the arch wiki has a great summary on different kinds of touch pad settings including for a better palm detection:
synclient PalmMinWidth=4 PalmDetect=1
This works excellently for me - and I have a new system with a rather large touch pad. Enjoy! And as always: Please share your experience and ideas!
This error occurred to me with a Fritz Box as access point and WPA/WPA2 mixed mode. The first time the camera still connected, later attempts failed. After switching the network mode to WPA2 only, it worked again.
Update: I've upgraded to Firmware v. 1.1 and the issue disappeared.
Otherwise you can probably try resetting the camera settings. Good luck!
You know that when you use a lock screen, it's often quite easy to know your combination by simply looking at the grease traces of your display? Well now there's finally an app against that. And it's called SmearSafe. Apparently, it was developed by people connected to the University Stuttgart. I've checked the whois entries and saw that the domain hcilab.org is really registered to the name of the professor of the University Suttgart. Further than that, I can't really validate their identity. But it appears ok.
The app works by changing around the image in a way that the way you have to move your fingers is different each time. I.e. it turns, distorts, moves and mirrors the image in different ways. This way the smears get mixed up and it's pretty much impossible for someone who sees your hand movements to guess your login. Of course, it may also require a bit more brain power on your side.
Let me know how it goes for you! Note: I had to set it up twice before it actually started to work on my phone. And it will request admin priviledges to be able to unlock your screen without being set to root.
I've recently found out the USA service seems to end. It's still going on in other countries, though, apparently. Well the margins in the VoIP business must be smaller than I thought. Very sad, as Sipgate used to always have great service and good quality in my experience. But I guess it's hard to compete with Google in the same market.
Agedu is a great tool, as it doesn't only show you where the data is, but also how long ago it was last accessed. It's a bit sad that the tool is not as straight forward to use as it could be. But here's a guide.
Basically you first call agedu -s <somedir>, then agedu -w to start a webserver and then look at the webpage that the latter command tell you about.
Suspending to RAM is allows the system to quickly wake up. But Suspend to Disk allows the system to completely power off, saving more power. That's why I've written a small script for modern Linux systems, which wakes up the system from S3 (memory sleep) and puts it into S5 (hibernation) mode. Also, it prevents you from losing data, because eventually your system's battery will run out.
The Samsung Notebook already runs pretty well out of the box with Ubuntu 12.04.3. All this information is used at your own risk, you might destroy your device!
You should be careful about using efi, as you've probably read - or you might brick your notebook. Although the 535 series is usually not explicitly listed as having problems in this regard, better be careful and disable secure boot and boot in CSM mode.
AMD apu/cpu tweaking
After a modprobe msr and modprobe cpuinfo you can use the turionpowercontrol tool to enable frequency boost for your cpu: (this is potentially DANGEROUS!)
sudo ./TurionPowerControl -psienable -boostenable
In Windows, the FN-F11 combination slows down the system's fans to make it pretty quiet for usual use, although the fans already run less in Linux than in Windows. There is a special kernel module for this purpose here: easy_slow_down_manager, the dkms package download is here, after installing it successfully simply echo 1 > /proc/easy_slow_down_manager.
Wifi after Suspend
The rfkill force locks the wifi after suspend to ram (S3) mode in my experience. The problem is fixed in Kernel 3.8, which you can get from the Ubuntu kernel PPA. You will need to install the fglrx-experimental-12 driver package (sudo apt-get install fglrx...), which works with this new kernel. To automatically enable wifi after resume, create a pm file:
rfkill unblock all
rfkill unblock all
rfkill unblock all
exit 0' | sudo tee /usr/lib/pm-utils/sleep.d/000-535-rfkill
chmod +x /usr/lib/pm-utils/sleep.d/000-535-rfkill
Video Acceleration (VA-API)
You can use xvba with vaapi to get video acceleration with vlc and mplayer-vaapi. For mplayer-vaapi you need a special package from a ppa:
With kernel 3.8 and the new catalyst 12 video driver, you'll need to manually install the xvba-vaapi backend. All you need to do is copy two libraries, though. (For some reasons the package is set to conflict with the newer driver, but really the same library is actually compatible and would still work. Feel free to inform the package maintainers for a workaround.)
Something I'm not sure how to fix yet is that the notebook can become become slow when the AC adapter is *plugged in*. I have no idea why this could be the case, but I've seen several reports about it.
There is no acceleration for the Adobe flash player plugin. However, this seems to be coming up, as AMD has just provided vdpau accelaration for its open source video drivers.
Let me know how this all works for you! Everything at your own risk!
But if you're in a different country or use a non-US version, your Gmail folder names are different. In German, the folder name is: "[Google Mail]/Alle Nachrichten", so the correct setting for getmail is:
