Package: firmware-amd-graphics Version: 20180825+dfsg-1~bpo9+1 Laptop Information - Inspiron 5775 - AMD Ryzen 5 - 2500U CPU - Radeon Vega 8 GPU (Shared with CPU)
Kernel: 4.19.0-0.bpo.2-amd64, 4.19.16-1~bpo9+1 - Without Package Debian Stretch works fine with one config change: /etc/default/grub/ * see notes Steps to Reproduce: * This assumes stretch-backports is installed * #1. Install ATI Firmware: #sudo apt-get install -t stretch-backports firmware-amd-graphics #2. Reboot Install: # After reboot - kernel loads just fine but then when it hits the gnome-shell login screen the system locks up (cursor has no movement) and only a grey background is shown. Here is part of my log what I seem to show: gnome-session: gnome-session-binary: WARNING: App 'org.gnome.Shell.desktop' exited with code 1 Without the firmware-driver I can get gnome-shell to launch just fine however for my laptop I have to set the following up for proper screen booting: /etc/default/grub/ (see below). Even commenting these in/out still produce a lock when the firmware is installed does not lock when firmware is not installed. * Yes: this is close * > GFXMODE=1920x1080x32 > GFXPAYLOAD=keep Last Note: Running Fedora live with vga=3d4 or vga=755 seems to boot up: I have less lockup problems and HDMI is fully supported. Right now even with the firmware there is no HDMI output using Debian Stretch. I don't know if this has to do with a newer firmware of Fedora for AMD ATI and/or the Kernel or if Mesa also is updated such that for the most part things are working. I expect Buster to be working fully if what is pulled in is updated.
