Raul Delgado's questions

could someone help me compile this Compton fork?

https://github.com/tryone144/compton/tree/improved_fbo

.I have followed the instructions here: github.com/tryone144/compton/blob/improved_fbo/README_orig.md

I installed the dependencies, I am really a bit lost in everything I have to do. It would be a great help if someone could take the time

I still don't understand how to clone from git, so I downloaded the zip, clicking on Code and then the clone or download button, then extracted it and followed the instructions in README_org.md file. I installed the dependencies, then opened a terminal in the extracted folder and ran:

Hi, sorry for the lack of knowledge, maybe this is a stupid question. Is it necessary to install java after installing Ubuntu for the correct operation of the system? I mean for a standard user who only uses the pc for some tricks and basic things.

I have Ubuntu 18.04 xfce4.14 desktop environment. I am using Compton for desktop effects. I have read many forums about screen tearing in videos, I really have not had such a problem, just a flickering in the windows when I resizing them, I did not like this and I decided to fix it. I assumed it was related to the graphics driver. I have integrated graphics from Intel. I followed a tutorial to update the Intel drivers as follows:

$ sudo add-apt- repository -y ppa: oibaf / graphics-drivers $ sudo apt update $ sudo apt install xserver-xorg-video-intel

So far so good, I rebooted and didn't really notice any changes except when running the command: $ xdpyinfo | grep DRI

Shows: DRI2 DRI3

Prior to the update it showed DRI2 only. Still the windows kept flickering when resizing them. Then the software update application notified me that I had new updates available from that repository and I gave them update. When it finished, without errors, I rebooted and could no longer start my graphical interface. It stayed on black screen

Starter user manager for UID 120

From there it did not happen, then I read that it was incompatibility of AMD drivers with gdm3, I managed to save my desktop following tutorials but the graphic performance was worse than before, when executing the command:

$ inxi -Fxz

In the graphic section: Driver: vesa (unloaded: modesetting, fbdev) OpenGL: renderer: llvmpipe (LLVM 10.0.0, 128bits) Version: 3.3 Mesa 20.2.0-devel (git-794334 2020-05-25 bionic-oibaf-ppa)

Before this last update it said: Driver: i915 OpenGL: Redender: Mesa DRI Intel HD graphics 510 (Skylake GT1) Version: 4.5 Mesa 18.0.0-rc5

I couldn't go back by uninstalling these drivers as I read in some tutorials. Neither with the command:

$ sudo ppa-purge ppa: oibaf / graphics-drivers --auto-remov

They give me some mistake that I don't remember. Conclusion, I had to re-install to the point where I add the repository and update only xserver-xorg-video-intel.

The question is: Why if I don't have amdgpu graphics, ATI ..... installed nouveau and all those drivers that damaged my desktop? They have returned to me but I do not plan to update them. I have solved the problem of window flickering by creating a file named 10-Intel.conf in /usr/share/X11/xorg.conf.d/ with the content:

Section "Device"                Identifier "Intel Graphics"                Driver "Intel"                Option "AccelMethod" "glamor"                Option "TearFree" "true"                Option "DRI" "3” EndSection

After this setup, the glmark2 score was 729. Before it the result was 447. Now the blinks are over, everything feels running much lighter.

Regarding the name of this file, in some forums I have seen that they are named 20-intel.conf and in others 10-intel.conf is there any difference in terms of operation? Without further thanks in advance for any help.

I have installed ufw and gufw in Ubuntu 18.04 with XFce4.12 environment. I was exploring its configurations, then I looked for some tutorials to configure it and when I run sudo ufw it returns this to me:

ERROR: not enough args

Then I run:

$ sudo ufw enable
Traceback (most recent call last):

    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xac in position 4: invalid start byte

I can no longer start it, I have uninstalled and reinstalled it and it remains the same, any help please?
