desgua's questions

Facebook Gameroom is a Windows app for games that can be downloaded from: https://www.facebook.com/gameroom/download/

I have tried to install it with Ubuntu 18.04 default Wine (1.6) and also with Winehq from upstream (https://wiki.winehq.org/Ubuntu).

I have installed and tested dotnet 45, 46 and 461 with winetricks.

The "FacebookGameroom.exe" installer get stuck with a message that says "Connecting" when I run wine FacebookGameroom.exe.

Interestingly I get more progress running natively with mono mono FacebookGameroom.exe, it goes through "Connecting" > "Downloading" > "Installing" but then get stuck too.

My computer is an HP notebook with Intel i3 and Nvidia and SSD. Proprietary graphics drive are installed. I installed Ubuntu 18.04 as a new installation (instead of upgrading from 16.04).
I really miss the responsiveness of Ubuntu 16.04.

The overall cpu load is less than 10%. "top" shows Gnome-shell at 3.3%, and Chrome at 2%.

The CPU/GPU temperature is around 57 Celcius.

RAM usage with a lot of tabs opened in Chrome are still less than 2 of the 4 GB available.

Also I have tweaked "IO Schedulers" to deadline by doing

     echo deadline > /sys/block/sda/queue/scheduler
     echo 1 > /sys/block/sda/queue/iosched/fifo_batch

I also disabled "smooth scroll" on Libreoffice which gives me the best results in tweaking but the computer still feels sluggish.

The advanced tool to configure Compiz (CompizConfig Settings Manager - CCSM) can use two backends (2017):

ini = Flat File Configuration Backend
gsettings = GSettings Configuration Backend

You can choose the Backend opening CCSM and clicking in "Preferences" or editing the ~/.config/compiz-1/compizconfig/config file.

Years ago Compiz would crash using some configurations and saving using GSettings Configuration Backend (but would not crash with the same configuration and Flat File Configuration Backend).

Besides of that, the GSettings Backend is the default in a new Ubuntu instalation (in contrast with others distros (1)).

Is there any advantage using one over the other?

I messed up with my files... Again... Now I am concerned if I will be able to login again once I logout. Is there a way to test if the essentials files are all there?

1. My home was encrypted during the installation (Ubuntu 12.04).
2. By login I mean boot Ubuntu into lightdm, type my password and be able to use my files which are encrypted and should be decrypted after the login.
3. By messed up I mean I have moved all my ".xml" files under user directory. I do not care that much for the configuration of the applications, neither for my keyboard shortcuts as I have a backup for them.
4. I can run ecryptfs-unwrap-passphrase ~/.ecryptfs/wrapped-passphrase and it shows me the passphrase.
5. At ~/.ecryptfs I have auto-mount auto-umount Private.mnt Private.sig wrapped-passphrase.

One Ecryptfs manual says:

$ man ecryptfs-setup-private


FILES
   ~/.ecryptfs/auto-mount

   ~/.Private - underlying directory containing encrypted data

   ~/Private - mountpoint containing decrypted data (when mounted)

   ~/.ecryptfs/Private.sig - file containing signature of mountpoint passphrase

   ~/.ecryptfs/Private.mnt - file containing path of the private directory mountpoint

   ~/.ecryptfs/wrapped-passphrase - file containing the mount passphrase, wrapped with the login passphrase

   ~/.ecryptfs/wrapping-independent  -  this  file  exists  if  the wrapping passphrase is independent from login passphrase

May be those all are the required files?

Edit:
I rebooted the computer and although I have lost the configuration of applications and Keyboard Shortcuts I was able to login again. So I can say that no xml file is needed to login into an Ubuntu encrypted home.
But the question remains valid: is there a way to test if one will be able to login in the next boot?

Very unfortunately I have moved all my xml files into one folder (I was at /home/desgua/ when I run find . -name '*.xml' -exec mv {} ./logs/ \;.
Now I am very afraid of turning off my computer and not be able to turn it on again. I have my /home/desgua/ folder encrypted during the installation.
Is there any essential xml file that I should be aware of?

ps.: One example of fundamental xml file is ".encfs6.xml", which are required to mount two folders that I had encrypted. Fortunately I recovered it.

I rebooted the computer and although I have lost the configuration of applications and Keyboard Shortcuts I was able to login again. So I can say that no xml file is needed to login into an Ubuntu encrypted home.

I use my laptop in two offices, each one with its printer connected via USB. Unfortunately I keep sending documents to print to the wrong printer. I would like my documents to be send automatically to the attached printer. Does someone know how?

I can not figure out what I am doing wrong. The package builds ok with quickly package, I could submit it, but I can not update my ppa. Here is what I got:

desgua@desguai7:~/quickly/sbk$ quickly share --ppa sbk
Get Launchpad Settings
Launchpad connection is ok
..........An error has occurred when creating debian packaging
ERROR: can't create or update ubuntu package
ERROR: share command failed
Aborting

Edit

The name of my ppa was wrong, but even using ppa:desgua/sbk still doesn't work:

desgua@desguai7:~/quickly/sbk$ quickly share --ppa ppa:desgua/sbk

Any ideas? How could I troubleshot this error?

How do I install the new beta driver for Nvidia?

With Ubuntu before 12.04 I could do this:

1) Downloaded it from the site www.nvidia.com

2) Logout,

3) Move to tty1 (Ctrl + Alt + F1),

4) Stop lightdm or gdm (sudo service lightdm stop)

5) Remove any nvidia driver (sudo apt-get remove --purge nvidia-current nvidia-settings)

6) Cd into downloaded folder (cd ~/Downloads/)

7) Run the installer (sudo ./NVIDIA-Linux-***.run)

But this doesn't work anymore, i.e., after reboot I am presented with a very low graphic resolution (something about 320 x 400).

I've seen some suggestions by using gconf-editor but it doesn't seem to work anymore. The option may have been removed (see).

Is there another way to increase Totem buffer size so when I see a video trough LAN it doesn't lag?

When I make a custom shortcut with gnome (gnome-control-center keyboard) I can't set it to a command. Why?

Example: I can't set a shortcut for sudo apt-get update. Instead I must first invoke a graphical terminal, then bash, then execute the command (something like: gnome-terminal -e "bash -c \"sudo apt-get update ; exec bash\""

Also is there another (better) workaround?

How can I remote access my computer desktop that is behind a router with my Android Tablet?

As we are going toward Gnome 3, I would like to know what to expect. May be a more responsive desktop, faster startup of apps? Or should I start to thinking in another DE if performance is a concern?

I am wondering about a Gnome-3 vs Gnome-2 comparison, not Gnome Shell vs Unity.

I often get stuck at the boot on battery.

I can suspend and hibernate without any trouble (even on battery).

If I plug the energy cable everything goes right most of the time (edited June 13).

Adding "acpi=off" doesn't solve the issue.

Disabling power save from LAN at BIOS doesn't solve this too.

Memory test seems to be ok:

I can even compile a kernel without a problem:

Has someone a tip for this?
(I have the same questions marks in my mind as the image shows if not more :-/ )

obs.: this is an upgraded installation from Natty alpha.
edited I (May 22): I've installed a brand new final 11.04 and got the bug again.

edited II (June 13): I thought it was solved but it is not. After spending eight days off, the same problem happened even with the power cable connected. I had to reboot about 6 times until success.

edited III (June 14): I can boot (even with battery) if I disconnect the cable and take off the battery for a few seconds. This lead me to conclude that maybe something is kept into memory of some hardware. Maybe or maybe not related but I also have touchpad issues (jumps) with this machine.

edited IV (June 25): I opened gconf-editor and went to apps > gnome-power-manager and disabled everything possibly related to suspend or hibernate. No help.
Also I grabbed a Fedora live usb pendrive and got the same problem:

So I think it is a hardware problem related issue.

Suppose I am trying some distro (with Gnome) and I like some theme. How can I copy for installation in another computer?

I want to change the shortcut to scroll. Instead of using the edge of my (buggy) touchpad (see this), I would like to make my own shortcut with the keyboard keys.
Is it possible?
Thanks in advance.

I want to make my own shortcut to increase or decrease brightness.

I don't like the default shortcut of my HP laptop (Fn + F7 to decrease and Fn + F8 to increase).

Is it possible?

How can I make some file impossible to be deleted by user even if it is under his/her home folder?
