After installing Ubuntu MATE 16.04 in a Dell G7, I noticed small freezes and after inspecting the syslog I found errors with "Microcode SW error detected".

This is the relevant syslog output:

What should I do? Is this a known issue?

Did anyone else notice a sudden increase in booting time after a recent update (maybe, 2 or 3 weeks ago) in Ubuntu 14.04. After showing the Ubuntu logo, there is a black screen that takes a lot of time to finish. After that, Ubuntu loads the desktop and everything runs as usual.

This is happening in a laptop Dell Inspiron 1545 (Pentium 2GHz and 8GB RAM).

I have installed bootchart and this is the image produced:

enter image description here

If I'm reading the output correctly, it takes 1 minute and 28 seconds to load.

I'm almost certain that I haven't installed anything recently. Does anyone know what could be the cause?

UPDATE

It takes 55 seconds to show the black screen and lasts 43 seconds until the desktop appears. A few seconds before that, it is possible to move the cursor. It looks similar to the interval with low CPU use in the upper graph from the bootchart output.

I have been experiencing a few problem with my monitor HP TS-19SV even with the newly released Ubuntu 12.04 (although, this had happened before on Ubuntu 11.10, 11.04, 10.10 and 10.04. Basically, from time to time, when I start my computer and got to the Ubuntu's desktop, I see quite a bit of black lines next to my cursor and when I move the cursor up to the limit of the screen, the desktop fills with those weird lines. Something similar happens when a move the cursor at the bottom of the screen. Obviously, an image will be more helpful than my attempt of description:

Look at that rectangle next to my cursor:

When I reach the bottom of the screen:

When I reach the top of the screen:

Has anyone experienced something similar to this?. How can I solve it?.

Thanks a lot

UPDATE:

After running sudo lshw -C video I get this:

UPDATE II: The answer given by Luis Alvarado solved this issue. There is still a weird fading effect when I shut down / Log out that happens when there is a process waiting to be closed but for the most part, everything is working great.

I recently bought a Wacom Bamboo Pen & Touch CTH460L. I installed doctormo's PPA, however, the pen functionality didn't work and the touch was very glitchy (when I touched it, it immediately double clicked and began to drag elements in the screen).

I tried to configure it using the wacom-utility package in the Synaptic Package Manager (version 1.21-1) but that didn't work either. Then I followed this post (#621, written by aaaalex), and after some problems trying to restart Ubuntu (graphics related problems), the pen works fine (it could be better, though) but the touch functionality doesn't work anymore.

Currently I have installed xserver-xorg-input-wacom (1:0.10.11-0ubuntu7), wacom-dkms (0.8.10.2-1ubuntu1) and wacom-utility. The Wacom Utility only displays an "options" field under "Wacom BambooPT 2FG 4X5" but no other option to configure it.

What is the correct way to get this tablet working on Ubuntu 10.04?.

By the way, currently I can't start Ubuntu properly when the tablet is connected (in that case, Ubuntu start in low graphics mode). I need to connect it later.

UPDATE: I uninstalled xserver -xorg-input-wacom, and wacom-utility because one of them prevented Ubuntu to start normally. I only re-installed wacom-dkms 0.8.10.2-1ubuntu1. The pen is working but no touch functionality. The side buttons don't work either.

Thanks in advance.
