I've just become a fan of this amazing piece of software. Just everything about it seems to be perfect. The noise reduction is stunningly good while preserving details. The sharpener brings out crips details down to the single pixel. You may even be able to tether you camera via USB and control your camera's settings and shooting with live view directly from your computer. It even does some tone mapping, imports GPS data into your photos and more. I was going to say now it only has to take the photos itselt. But with tethering, in a way, it already does. :)
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:
I've been thinking about trying it for a long time. Once a while ago I installed Word with Crossover for Mac for a friend. It worked pretty well.
But now I've tried the new one with my old Linux sytem (Ubuntu 9.10) and a brand new Office 2010. I'm quite happy that the backwards compatibility is so good. As you know from my browsers blog entry, (for some good reasons) this is rather rare in the Linux world.
And it works stunnigly well. Office installed without a glitch. I have only tried a few things, but startup is fast, use is snappy and memory usage quite low (~150 MB for Word in CrossOver.) Also, the integration is flawless. I get "start menu" entries automatically. Word files open with word out of the box and so on.
I'm quite fascinated. I wouldn't have thought that it's this easy to get things running. Also, from what I've seen I think CrossOver for Mac + Office is probably a better option than Office for Mac...
After you run the jar, the app automatically discovers the computer
and offers to control it. It works like the touchpad on your notebook.
You can click by tapping, scroll with a two finger swipe, and zoom by
spreading your fingers. It works surprisingly precise and smoothly.
The setup is an absolute no-brainer. The app comes without apps and
only requires network setup.
- left click
- auto-discovery of computers
- entering letter by letter and short words via Swype
What didn't work in my test:
- long words with Swype (1.4 beta)
- double click
- right click
- right click e.g. via two finger tap
- double click via double tap
- disable the display's backlight to save battery
- better swype support
If your kernel crashes every once in a while and you want to find out
what happened and/or create a good bug report so it can get fixed,
here's all you need to do in Ubuntu 12.04+:
sudo apt-get install linux-crashdump apport
This automatically installs and sets up a crash kernel to be loaded
via kexec in case of a kernel panic. And it installs apport to be able
to easily report the crash to Ubuntu. The logs will be in /var/crash.
No matter how I configure my Samsung SSD, it does not automatically
enter a standby or sleep mode. It does with with hdparm -y/-Y
manually, but that's the only way. And of course during the next
reader it's automatically activated again. hdparm -B is "not
supported", hdparm -S does not seem to have any effect, with 1/253/254
settings. I've used lm-profler to find and stop any accesses to the
I'm using the sata_sil24 driver with a Sil 3531 SATA controller and as
stated a SAMSUNG SSD 830 with firmware CXM03B1Q. By the way, hdparm -I
tells me that it doesn't support DIPM, unfortunately. I've tested
Linux kernels up to 2.8-rc2.
The reason it's important to me is that I found out the system uses >1
W less power with the SSD in standby mode. And while the SSD uses less
power during disk access, the disk idle power usage is actually higher
now than previously with my plain old spinning hard disk.
Mostly I post fixes, this is just a problem I have. I would appreciate
any hints in the comments. Thanks!
