OpenSuSE 13.2 / TeamViewer "not ready", "connection error"

After some years of using teamViewer with no problems, yesterday, out of the blue, it started to give a "connection error". Reboot didn't work, but the solution is, actualy, a restart of TeamViewer. So, just open a terminal and type:
    sudo teamviewer daemon stop
    sudo teamviewer daemon start

OpenSuSE 13.2 - connect to Windows Remote Desktop

     In order to remotely connect to a Windows Server 2012, I have tested 2 programs: KRDC and Remmina. Both works quite fine, with a plus for Remmina, which allows printer sharing. Let's take a look at them.

KRDC

     KRDC is made by KDE and I found it installed by default. At least, I don't remember installing it by myself. It does not require anything special, it just works, even on a slower connection. It is easy to configure. It has a "Media sharing" option which I couldn't figure out what it does. It does not has a "Printer sharing" option and I couldn't find a "File sharing" option. Maybe the "Media sharing" option can be used, but I don't know how.

     In short, for a simple remote control it's just what you need, especially on a KDE desktop.

Remmina Remote Desktop

     Remmina is more sophisticated. It can be easily installed through Yast: just open and search for Remmina. Pay attention, you must also install remmina-plugin-rdp in order to connect to a Windows Remote Desktop.

     Once installed, it is about just as easy to configure and use as KRDC. Subjectively speaking, I think it requires a fastest connection connection. However, it has "File sharing" and "Printer sharing". In a very strange way, printer sharing will work only if you enable the "Sound" option as "Local". Concerning printer, in my case it didn't print the whole page no matter what setting I tried: the first 3 lines were just missing. I don't know it it was a driver-problem on Linux side or a Remmina-problem.

     "File sharing" is working fine. Just select a folder in configuration options and it will appear as a virtual drive on Windows side. No problems.

My conclusion:

     Remmina is more complete. However, if you need to rely on it for printing, make sure you test it.

[UPDATE]
     For some strange reason, this morning Remmina refused to connect to server, saying "Unable to connect" The solution was to delete the file /home/neklar/.freerdp/known_hosts

OpenSuSE 13.2 / ACER laptop - system goes to sleep

     I have a ACER laptop for quite some time (2009). Most of the time I use it as a desktop computer: the lid is closed and the image goes to a  external monitor. Of course, I disabled the lid-event in order to prevent the system to go to sleep. I never had any problems with that.

     However, this morning, after applying some updates, the system started to behave differently: it was going to sleep every 20 seconds or so, without any obvious reason. I checked all the settings and everything appeared to be normal. If I opened the lid, it was not going to sleep anymore, but when I closed it back, the same problem returned. Ok, I can stay with the lid open, but I don't like it that way.

     So, I have some possibilities:

          1) the system is too old and it's showing its age

          2) there is a new setting after the update and I cannot found it

          3) there is a bug in the update (either a driver or a setting)

     I don't have an answer, but after google-ing a while I have a solution (or, at least, a workaround): I forced the system to ignore the lid.

1) Open Dolphin a SuperUser (you need root access)

2) Edit the file /etc/systemd/logind.conf

3) Add (or modify if it already exists) the following line: HandleLidSwitch=ignore (also make shure it does not have the # character in front of it; this character marks a line as comment and it will be ignored)

4) Save and reboot

DropBox / OpenSuSE 13.2 / SysTry icon=?

For some strange reason, DropBox icon does not appear in SysTry on OpenSuSE 13.2. I couldn't find a solution or a workaround, so... I designed my own application.
Here it is:
https://www.dropbox.com/sh/if0g7xwgcksdow5/AACREupcxQh_1pYy7JYHwIRDa?dl=0

In Lazarus/FPC, of course.
OK, it's not a complete app: it just reads the status of the Dropbox an changes the color of the SysTry icon, but that's good enough for me

Games on OpenSuSE

Here are some games and some issues I came across

Jedi Academy
There is a port for Linux of Jedi Academy. However, I have the old Windows versions and it runs excellent in Wine, once you can make it work. So, here are the steps:

1) Make sure that your CD-Rom is configured correctly in Wine. Open WineCfg

2) Install the game (should not be any problems)If the game stacks when you should change the CDs, do the following:

   a) Create an ISO image for each CD an put it somewhere where you can find it (I created a directory in Documents

   b) Create 2 directories (ISO1 andI SO2) and then 2 virtual devices (one for each image) like this:

sudo mount -o loop /home/neklar/Documents/JediAcademy/jediAcdCD1.iso /home/neklar/Documents/Jocuri/JediAcademy/ISO1

sudo mount -o loop /home/neklar/Documents/JediAcademy/jediAcdCD2.iso /home/neklar/Documents/JediAcademy/ISO2

  c) Open WineCfg again and mount those 2 devices. go to advanced properties and specify that they are CD-ROMs

   d) Install the game

3) The Game's executables are jamp.exe (multiplayer) and jasp.exe (single player). You must locate them, because they have to be modified. Typically, they should be in Wine directory, like mine: /home/neklar/.wine/drive_c/Program Files/LucasArts/Star Wars Jedi Knight Jedi Academy/GameData/

4) A good editor to do the trick is Okteta. If you don't have it, install it (package okteta)

5) With Okteta, open the file jamp.exe. Locate the expression GL_EXTENSIONS %s , replace 's' with 'p' (should look like this: GL_EXTENSIONS %p ) then save. Do the same for jasp.exe. Start the game from one of those files (single player or multiplayer) and have fun!

For me, it works on maximum resolution and with all details, both single and multiplayer

Pay attention: There is a noCD pach (or crack ?!) for it, but it will not work with that.

OpenSuSE 13.2 / Dell Inspiron 1501 / Broadcom B43 wireless solution

I've installed OpenSuSE 13.2 on a older Dell Inspiron 1501 laptop. Everithing was fine, except for the wireless card which refused to work. After searching the internet I found out that the problem was the B34 driver. So, here is my solution:

1) Make sure that the b43-fwcutter package is installed. Open Software Management, search for it and install it if it's not

2) Open Dolphin as SuperUser and find /usr/sbin/install_bcm43xx_firmware
Right click on it and select Actions>Run in Konsole (so that you can see the output).

3) Reboot.

OpenSuSE 13.2 / Snapper / free space on ROOT

     I installed OpenSuSE 13.2 a while ago (about 5 months) and I noticed that the used space on ROOT was growing steadily. I ignored the issue until yesterday, when the free space on root was only 760 MB (from a total of 20GB).
     After searching the internet for a while, I concluded that "Snapper" was responsible for that situation.
     As far as I can tell, Snapper is a backup system, so it creates periodically "snapshots" that can be used for recovery. Since I never used it in about 3 years of LINUX, I decided that I don't need this application, and I removed it. Result? About 9 (nine) GB free on rood and a visibly faster system. I admit though that my system is no longer a "modern" one, but it's doing its job: Acer Core 2 Duo 2200 MHz, 3GB RAM, 300GB HDD.
     If you decide to remove the Snapper, the files created for recovery must also be removed, otherwise you accomplished nothing (except the fact that it will stop growing). So, before you uninstall, you must start Snapper from your program list and there you will find all of the backup files ever created, so you can delete them
