AMD Radeon R5 230 or HD 6450/7450/8450 does not work


#1

Unfortunately I ran into the following problem:

When using my Radeon R5 230 as the primary graphics adapter, the screen resolution is automatically set to 1400x1050 (4:3) on a 1080p monitor. There is no way to change it. Also, the output is pretty laggy & if I open “settings” > “details” > “info”, “graphics” says “llvmpipe (LLVM 5.0, 256 bits)”.

If I type “lspci”, I get the following output:

00:00.0 Host bridge: Intel Corporation 4th Gen Core Processor DRAM Controller (rev 06)
00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor PCI Express x16 Controller (rev 06)

04:00.0 Multimedia audio controller: VIA Technologies Inc. VT1720/24 [Envy24PT/HT] PCI Multi-Channel Audio Controller (rev 01)

So it is recognized by PureOS, why doesn’t it work properly?

Is there actually any GPL-based driver for the Caicos GPUs on PureOS?

Or can you instead recommend some AMD-based PureOS-compatible PCIE-graphics cards?

PS: I hope people all over the world, that develop proprietary soft- and hardware, will d*e immediately.

It requires proprietary firmware.

Yes, but it requires firmware.

Some very old hardware (r300 codename).

Thank you for your quick and kind answers :slight_smile:

So I have another question then. I just read somewhere, that Matrox has some “open source” drivers for their graphics cards for GNU/Linux. But in contrast to AMD, there is nothing said about some proprietary parts in drivers, just the loose term “open source” is used. Does that mean, that one of the following cards would work with PureOS?

G55-MDDE32F
M9120-E512F
P69-MDDE128F

Also, I found the following packages in apt by searching for “matrox” and the last one looks promising to me:

fbtv/green 3.103-4+b2 amd64
television viewer - Linux framebuffer application

matroxset/green 0.4-9 amd64
switch output modes, including TV out, of Matrox video cards

xserver-xorg-video-mga/green 1:1.6.5-1 amd64
X.Org X server – MGA display driver

So please, let there be firmware :smiley:
