Bug#944420: Fixed in 5.5
The green screen lockup issue is fixed in 5.5. I've tried 5.5rc5 from experimental. While it crashes a lot and shows graphical corruption in XFCE, I don't not get the green screen lockup. I've also compiled 5.5.6 myself. With that kernel, crashes are a lot less common (though they still happen in games sometimes) and the graphical corruption is gone too.
Bug#944420: Can't reproduce when using 5.1.21 from Ubuntu packages
Today, I've also installed a 5.1.21 kernel from Ubuntu on my Debian GNU/Linux testing system, and logged into XFCE thrice. I did not see the green screen crash with that kernel, though once I got a crash (system frozen, only mouse pointer still moveable) a few minutes after logging in.

Bug#944420: Two more confirmations
Two more Manjaro users with of the green screen hang on XFCE start using 3400G with a 5.x kernel: One in the thread mentined above, the other in https://forum.manjaro.org/t/kernel-question-amd-ryzen-5-2400g-with-radeon-vega-graphics/106683
Bug#944420: Bug confirmed with 5.x kernel on Manjaroo, too
Apparently someone has the same problem (AMD 3400G APU, mainboard with B450 chipset, 5.x linux kernel, green screen crash just after login) using a RC of linux 5.4 on Manjaro: https://forum.manjaro.org/t/manjaro-with-ryzen-3-3200g-vega-8-any-experience/110497/18
Bug#944420: Also tried 5.2.0
I also tried an older 5.2.0 kernel: linux-image-5.2.0-3-amd64 5.2.17-1 The problem there is the same, but it seems I have a somewhat higher chance to make it to XFCE (in which I still see graphical corruption) than just getting a green screen (which I there see bit less than half of the time).
Bug#944420: Wrong info
I see reportbug added a lot of information from the system on which I submitted the bug report. Please disregard that; sorry for the noise. Do you need any further information from the system on which I see the bug that I should provide?
Bug#944420: linux-image-5.3.0-1-amd64: green screen in X
Package: src:linux Version: 5.3.7-1 Severity: important A few days ago, I installed Debian on a new Ryzen 3400G system (not the system on which I write this report, hope reportbug doesn't add any invalid information from the system on which I type this). I see graphical problems in X. I am not sure if the bug is in the kernel or elsewhere, but the kernel seemed the most likely candidate for the bug report to me. I have installed XFCE. After boot, I see the graphical login screen. After login, most of the time, the screen turns a dark green (so I don't get to see XFCE). Sometimes I do get to XFCE, but then there is graphical corruption. Despite the screen going green (which seems permanent - switching to a console won't help), I can still switch to a console and type blindly. That way I obtained the dmesg output I put at http://www.colecovision.eu/stuff/dmesg-log I have also tried with kernel options ioomu=off and iommu=pt init=nomwait, but neither one helped. The same system seems stable on Windows 10, so I guess it is not a hardware issue.

Bug#844604: [src:linux] Crash when resuming after suspend-to-disk
Package: src:linux Severity: important --- Please enter the report below this line. --- Whenever I try to resume from supend-to-disk, I get a crash with message: BUG: Unable to handle kernel paging request at a1c15685f000 […] The problem happens no matter if I use "s2disk" or "systemcl hibernate". Suspend-to-disk used to work up to a few months ago, but the problem already was there with Linux 4.7 and I'm not sure which was the last working version. On the other hand, suspend-to-ram still works fine. My memory hardware should be ok, as Memtest86+ does not find any errors. I see this problem on a Schenker S403 Ultrabook with an Intel Core i7-4500U processor and 16 GB of RAM. --- System information. --- Architecture: Kernel: Linux 4.8.0-1-amd64 Debian Release: stretch/sid 500 unstableftp.de.debian.org 500 testing ftp.de.debian.org 1 experimentalftp.de.debian.org --- Package information. --- Package's Depends field is empty.

Bug#641622: Screen corruption regression
Package: linux-image-3.1.0-rc4-amd64 Version: 3.1.0~rc4-1~experimental.1 Severity: Important There is a screen corruption regression for intel graphics. It sometimes appears spuriously and has been observed by multiple people. However there are ways way to reproduce it: In the free game simutrans, in fullscreen mode (install it from teh Debian package, start using "simutrans -fullscreen") I see the following problem: The lower about 2 cm of the screen don't update. They are black or carry the image from the game startup screen. They flicker once in a while, but otherwise the image stays the same. This makes the game practically unplayable in fullscreen mode. lspci output: 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c) 00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (secondary) (rev 0c) glxinfo: OpenGL vendor string: Tungsten Graphics, Inc OpenGL renderer string: Mesa DRI Intel(R) 965GM OpenGL version string: 2.1 Mesa 7.11 I have bisected this issue to the following commit: d74362c9e45689d8d7e3d4bcf6681c4358ef4f2e is the first bad commit commit d74362c9e45689d8d7e3d4bcf6681c4358ef4f2e Author: Keith Packard Date: Thu Jul 28 14:47:14 2011 -0700 drm/i915: Flush other plane register writes Writes to the plane control register are buffered in the chip until a write to the DSPADDR (pre-965) or DSPSURF (post-965) register occurs.

Using kernel command line i915.i915_enable_fbc=0 is a permanent workaround. There were some messages on the Intel-gfx list about this (titled "Screen corruption regression from 3.0 to 3.1rc4").
