My system consists of:
* MSI MS-7260 motherboard
* 2 gb of DDR2 ram (I plan to install two GB more)
* AMD Athlon 64 X2 Dual Core Processor 3800+
* Radeon HD 5750
* 250 gb WD SATA hard drive
* Viewsonic VA2216 VGA screen
I installed the OS with xfce through a usb drive created with Rufus and debian-9.6.0-amd64-netinst.iso -image.
My first trial was trying to install packages with apt-get. For some reason sudo apt-get install [package] didn’t work on the terminal. My friend pointed out that Debian does not have sudo by default… 🙂 What is the planned way of installing packages if not through sudo? Is it through using su root? Or is one supposed to install sudo or a program like it after installing the OS?
My second bigger problem is about screen resolution. The OS does not list my screen’s native 1680*1050 resolution as an option. I have googled for a solution and found eg. [this](https://askubuntu.com/questions/377937/how-to-set-a-custom-resolution). I type the cvt command with my resolution and refresh rate and then the xrandr –addmode with the copypasted content, but I get an error: “Failed to get size of gamma for output default”. Googling this error isn’t helpful.
I wondered whether the problem is that my GPU hasn’t got the right drivers. I tried googling for instructions for how to install ATI drivers on Debian, but had little luck finding understandable content. The packages I found (eg. [this](https://packages.debian.org/fi/jessie/firmware-amd-graphics)) I apparently don’t know how to use. Can you give some advice on this? Or do you think that my system (mainly GPU) is suitable for Debian at all?
Thank you everyone!
