problem with a new graphic card (GeForce GT 710) in Kubuntu 18.04

I have a matherboard graphic card and a new (GeForce GT 710) graphic card: my monitor is now connected via VGA to this new one. Installed proprietary driver of my distro, Kubuntu 18.04.
I have a problem with screen off: the screen is off 3 sec, but after that is still active, amd I can see the screesaver image, very obscure and off-centered. After, off 3 sec., after on and so on.

I tried to remove nvidia driver, but with nouveau driver I have many crash (in particular Falkon, but not only).

So I reinstalled the nvidia driver, but the problem is not solved: always the same bug.



EDIT

This is my modified etc/default/grub line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_rc6=0 i915.enable_fbc=1 i915.lvds_downclock=1 i915.semaphores=1 i915.enable_execlists=0"

I added this to avoid a crash problem when PC was in screen off. Maybe I have to re-modify that line?



EDIT

Modified that line, so: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash", but the problem is not fixed



EDIT

Modified grub, so: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvidia-drm.modeset=1", but the problem is still not fixed



EDIT

Modified grub, so: GRUB_CMDLINE_LINUX_DEFAULT="nomodeset", but the problem is still not fixed



Thank you for your help.

  • This possibly won't happen with the GeForce GT 710 graphics card if you connect it to an HDMI monitor with an HDMI cable.

  • Thank you: in effect my monitor is connected via VGA (and can be connected only so), and I need the hdmi port for a second monitor (e-ink).

  • Am I correct in assuming that the second e-ink monitor is working properly?

  • I have not received it yet, it should arrive on the 4th or 5th of December...

    Maybe the problem was the monitor: with another monitor (same PC) no problem!

How to change which sound is reproduced for terminal bell?

Image
3 Recently upgrade to 18.10 from 18.04, and using the terminal is becoming annoying: the new alert sound is a drip ( /usr/share/sounds/gnome/default/alerts/drip.ogg ), and the previous one is still located at ( /usr/share/sounds/ubuntu/stereo/bell.ogg ). My issue is that at the gnome-terminal, when autocompleting or pressing left BOTH sounds are reproduced, at the same time. I want to just have ubuntu/stereo/bell.ogg active, not both . At the moment I have been only able to reduce the volume of the alerts (but still both are played), or turn the alerts down (but I dislike both "solutions"). gnome-terminal 18.10 teminal-bell share | improve this question

Title Spacing in Bjornstrup Chapter, Removing Chapter Number From Contents

Image
up vote 5 down vote favorite 2 I would like to make it so that the vertical space below the title of each chapter is the same when using the Bjornstrup package (i.e. so that the descenders do not affect the spacing - as shown by the red arrow in the picture below). I think I'm fairly happy with the spacing around "A chapter", so I'd really like titles without descenders (e.g. "Contents") to have the same vertical spacing as "A chapter" below the title. I would also like to remove the large "0" in the contents title. Any help appreciated, as always. documentclass[11pt,a4paper]{book} % Packages[![enter image description here][1]][1] usepackage[left=3.5cm, right=3.5cm, top=4.3cm, bottom=4.25cm]{geometry} usepackage[utf8]{inputenc} usepackage{libertine} usepackage[libertine]{newtx

Can I use Tabulator js library in my java Spring + Thymeleaf project?

Image
0 I want to add Tabulator js to my java project. I added tabulator.min.js, tabulator.min.css to resources folder. After that added to my html page these dependencies as recommending in readme.md. <link rel="stylesheet" th:href="@{/css/tabulator.min.css}"> <script type="text/javascript" th:src="@{/js/tabulator.min.js}"></script> Now my tables view all elements, that I have in the html page, but not correct. In the documentation of Tabulator is example how to create header and table, var table = new Tabulator("#example-table", { columns:[ {title:"Name", field:"name", sorter:"string", width:200, editor:true}, {title:"Age", field:"age", sorter:"
