New Second Hand Graphics Card

I tend to postpone upgrading my computers until it either breaks down or it gets too cramped in performance/memory/etc. This tends to take a long time.

So a colleague of mine was upgrading his computer, and I managed to get his old graphics cards.

Seeing as I am on a budget, I was looking into what the difference in performance were for second hand graphics cards.

A lot of graphics cards are replaced because there are better ones, even though the old cards still work perfectly fine.

And he just happens to buy the latest and greatest, which is still a pretty good deal after 7 years, compared to what I buy.

My original graphics card

It's a AMD Radeon HD 5700 Series.

"New" graphics card

It's a Nvidia GeForce 770.

Notes

Some notes of mine.

type
you cannot tell any more what kind of graphics card it is from just looking at the physical hardware. With any luck you can find the manufacturer, but that's it. There's just not more room or not important.
external connectors
So, no more VGA connector. And of course my old monitor only has a VGA Connector. (Don't ask, I'll write about it in the next blog about how ancient it is). It gave me an excuse to upgrade my monitor.
internal power cable for PCI Express cards
The old graphics card had only one internal power connector, a 6 pin. The new graphics card had both a 6 pin and an 8 pin. Time to look in the attic for my spare cables box.
noise
it's rather depressing that the new graphics card has three fans and is more quiet than my old graphics card which has only one fan.
heaviness
with all the fans, and the cooling fins, this new graphics card is a seriously heavy beast in pure weight. I hope my motherboard can cope with it.
plastic
instead of screws, my case has plastic easy-to-use click-and-go thingies to fasten cards. Of course, plastic is the first thing to become brittle after several years. No surprises there.

All in all, I am extremely happy. Except for a few little surprises mentioned above, I had the entire setup working relatively quickly.

Problems with Resolution and My Monitor in Fedora Core 25

Well, my monitor always has been a bit of a problem child, but it worked, so I didn't mind.

I let it bounce once on the floor, but besides some slight discolouring in the lower-right corner, it was fine.

It reports EDID settings that are completely crap, but I got used to ignoring those, using xrandr.

XRandr settings that work for me

The following settings work:
xrandr --newmode "1920x1440" 339.50  1920 2072 2280 2640  1440 1443 1447 1514 -
xrandr --addmode VGA-0 1920x1440
xrandr --newmode "1600x1200" 235.00  1600 1728 1896 2192  1200 1203 1207 1262 -
xrandr --addmode VGA-0 1600x1200
xrandr --newmode "1280x1024"  159.50  1280 1376 1512 1744  1024 1027 1034 1078
xrandr --addmode VGA-0 1280x1024
xrandr --output VGA-0 --mode 1920x1440

Problem

Then I upgraded to Fedora Core 25, and my monitor showed me a handsome 1024x768, which was a disappointment to say the least. (I'm used to 1920x1440.)

Using xrandr gave me the cryptic error message:
bash-4.3$ xrandr --output XWAYLAND0 --mode "1920x1440"
xrandr: Configure crtc 0 failed
After some research I noticed that Fedora Core 25 is the first one to use Wayland1 as the default.

Solution

Switching back to the old Xorg2 fixed my problem.

Checking graphics card

bash-4.3$  lspci -nnk |grep -A 3 -i vga
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Juniper XT [Radeon HD 5770] [1002:68b8]
        Subsystem: ASUSTeK Computer Inc. Device [1043:0344]
        Kernel driver in use: radeon
        Kernel modules: radeon

Inkscape

Inkscape is a vector graphics drawing tool for Linux, which I've used in the past.

Fedora magazine has a series of articles on it, which I link to here.
