Hi all,
My trusty (old) Nvidia card died, and thus due to budget constraints I needed to use an AMD card I had as a spare.
I was planning on a new install regardless due to a new HDD purchase.
1. Successfully booted via live KDE DVD 18.3.0 using the radeon.modeset=0 option.
2. Successfully installed to the new HDD.
3. Unable to boot (HDD install), to a graphical desktop or access virtual terminal, as the display drops out during boot.
3a) although the radeon.modeset=0 is a liveDVD only option, if I apply this the boot will continue to initiating SDDM before going blank.
3b) without this option the display blanks out earlier in the boot process.
Card is a Radeon HD5690 (Redwood)
From the Grub command line the VGA mode selected is 1280x1024x32 and indicates 1920x1080 as 'preferred'.
1. Can someone advise on which option(s) to use to boot successfully into an xsession please.
2. Advice on what to include in an /etc/X11/xorg.conf.d/20-radeon.conf file will also be appreciated.
Cheers.

Have you tried
apt purge xserver-xorg-video-amdgpu xserver-xorg-video-ati xserver-xorg-video-radeon && rm -f /etc/X11/xorg.conf.d/20-radeon.conf
and rebooting, Can you get to the desktop ?

Hi Piper
Unfortunately I cannot even boot to the command line.
I've been searching for options to use from the grub boot menu to force vesa as an option in order to gain either desktop or command line access.
From what I've read in this forum and elsewhere if I can get to the command line I would need to do what you suggest then reinstall the drivers and non-free firmware.
I have been able to access the installed system via a live DVD and mounting the drives.
Though I was wondering if I were to chroot to the installed system from a live DVD if that would be an option?

Same problem here . No solution yet found
Come with moving to kernel 4.16
No problem when going back to 4.15
Kernel 4.16 modify drm .
See https://www.phoronix.com/scan.php?page=news_item&px=Linux-4.16-DRM-Highlights .
If anyone know a solution : thenks to you.

Provide any relevant logfile, otherwise no one is able to say anything.

How can I provide a logfile , I CANNOT get nor virtual console nor Xdisplay
What I see is : linux start loading kernel , with screen definition from grub , and when it will switch to the screen found by kernel , it hangs .
So no possible to get journalctl.
The only way to go back is POWEROFF / POWERON and boot with earlier kernel 4.15.15 towo 1
The PC with the problem is a laptop , I have also a desktop with kernel 4.17 and here no problem.
If you know which logfile you want , I can mount disk from lapotop on desktop and give it, but I do not know which file, and all log file ,I think it is too much
Thanks
-
You indeed can get a logfile from a failed boot. Do
yournalctl -b -1 after rebooting with working kernel, then you get the log from the boot with the failing kernel.
-
Just done 2 reboot on laptop[/size]Then journalctl -b -1 >log.txtBut file to large , so truncatedTruncated log.txt in attachHope you can helpThanks
-
Short question: Is storage of journald in a normal siduction-installation aktive?
-
The Logfile shows clearly a successfull startup of the system. Maybe the display output is wrong routed to a not connected output.
-
How can I find that ?
output correct for 4.15.15 , nok for 4.16.0 and up ?
With kernel 4.15.15 I have no problem , problem only with kernel from 4.16.0
There is only the kernel that is different , the rest of all datas are the same ?
Thanks.
-
Try booting with video=LVDS-1:d if it is not working video=LCD1:d as kernel parameter.
-
I analysed the log files for 4.15 and 4.17
They are differences in used adresses , can it be the problem ?
See log in attach diff_415_417.txt
Thanks
-
Since i don't know your hardware, i can't say many.You have 2 GPU it seems, maybe the kernel .17 is initializing the wrong GPU.
-
On laptop I can connect external display and I did that
Result :
Kernel 4.15.15 displays working both
Kernel from 4.16.0 no one is working
2 kernels coming from ftp.spline.de (siduction kernels)
But if I install 4.16.0-2-amd64 coming from deb.debian.org (debian kernel) , then the 2 displays are also working
And after analyse of config file for 4.15.15 and 4.16.0 , there are difference for
config_DRM_RADEON_USERPTR is Yes for 4.15.15 and IS NOT SET for 4.17.0
config_DRM_AMD_DC_PRE_VEGA IS NOT SET in 4.15.15 and is Yes in 4.17.0
Onething more : witk radeon.ko REMOVED , the PC can boot and I can access virtual console (no XSERVER)
Can some one rebuild the radeon module ? , it gives error here when I try , missing something , then someting other.
-
And I forgot :
Laptop , detection of RADEON RS780M HD3200
and RADEON RV710/MD HD4330/4350/4550
Desktop detection of RADEON RS690 X1200
Desktop has no problem ???
-
New Kernel is up with reverted changes, try it.
-
New kernel loaded and reboot : no changeSee harddisk busy , but no display , nor reaction witl ctrl+alt+f1 , only hdd busy
-
Then the problem are not these 2 config settings.
-
Ok , but it must be a problem with radeon.ko , if I rename it (no radeon anymore), PC can boot , and I have access to console,
With naturaly no xserver .I don't know what to doI stay with siduction 4.15.15 amd64, perhaps debian 4.16.0 amd64 is working.I investigate furter later , it depends on free timeThanks for your help.
-
Today updated to kernel 4.17.6-towo.1 , and problem disappeared
Can boot and get xserver when rebooting
Thus solved (for now)
