  • Does my graphics card share RAM with the CPU? How to find this information in Ubuntu?

    1 answer




When I bought a new laptop it had 4 GB RAM. Then after 1 month I added 4 GB RAM in the second slot. And it shows 7.88 GB RAM usable. After some time it showed 6.4 GB RAM usable and 1.4 GB hardware reserved. So I formatted and installed Linux. Now in Linux it shows only 6.2 GB RAM usable. I have talked to Dell customer care. And read many forum. I searched Google a lot, but nothing helped me.

    What did you try already? Before you formatted, what OS were you using? You can edit to add.

First of all, make sure your looking at the right stats. Perhaps you are looking at the available memory and not the total memory. Run this command in the terminal:



free -m


and see what it says.



Another possibility is your new ram is just bad, and may need to be replaced.

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...
