So I updated my Fedora 37 desktop and laptop installations and the desktop with an AMD 6800XT doesn’t have any display after GRUB but the laptop with a Nvidia 1050ti works fine. It boots into the Gnome DE and works fine. I have LUKS installed and I tried typing my password into the black screen and after hitting enter I can see my HDD light working but after 5 minutes or so still a black screen. I didn’t try to log in I just pressed the reset button. So upon the next boot I chose 6.2.15-200.fc37 from GRUB and it worked fine. I did journalctl -b -1 and compared it side by side to journalctl -b but I couldn’t really see any major differences. There were more bright yellow and red entries in the kernel that was working…
I could see that the system did boot though, it is as if the system is running but with the screen turned off. When I start the system I see the motherboard vendor / BIOS and then the monitor goes off, normally I would see Plymouth asking for me LUKS password. I’ve done some Googling but have only really found similar issues for people with Fedora 38, so nothing helpful so far. Happy to provides logs. System specs are:
Be aware that the topic is currently blurred between the issue with nvidia and the issue without nvidia. Initially, it was not clear that there are (at least) two issues. Focus on the points without nvidia (the nvidia issue is solved anyway).
I am aware that you have amd graphics, while the other user has Intel graphics, but it could still be linked.
Thanks for the reply. Yeah I did read that post and the bug report and dismissed it since I am on F37, using AMD, and I don’t see an underscore just a black screen. But yeah it could be related like you say. Funny that you say there is an Nvidia issue as my Nvidia based laptop works fine with those kernels.
Yes it does seem to boot but without any display. I’ve pasted that into https://pastebin.com/2mhQ6BsY which is private and will expire in 1 month. The end of the log is when I pressed the reset button.
It does not necessarily apply to all nvidia cards. Also, there might be differences in configurations and especially driver versions. If your nvidia works fine without the noted issue, ignore the nvidia issue stuff
Indeed, the logs you provided are from a 6.3.5 kernel. In this case, it could be a different issue. Or alternatively, F37 behaves different with the same issue than F38 (or some other software/hardware).
I have currently no time to tackle another issue, but when skimming your log, I see drm issues, which was also the origin of the nvidia problem.
With this in mind, I suggest to test the kernel 6.3.6, just to see if it maybe also solves your issue before putting more work in that than necessary: Please read my explanation in the other thread carefully: this one. However, the bodhi link I provided in the other thread does not apply to you. The page for you is: https://bodhi.fedoraproject.org/updates/FEDORA-2023-70b0935c41 (since you have F37, and the other user F38). The dnf command I referred to in my explanation shall appear on that page in 1-2 days.
If that does not solve the issue, please file a bug report, which I also explained in the other topic (here). Please read carefully what information you need to provide (and add the journal log!). If you opened a bug report, please post the link to the report here.
Yeah I saw them too but honestly I don’t know what that means so I didn’t mention it.
Thanks for that, I had a read and went to https://bodhi.fedoraproject.org/updates/FEDORA-2023-70b0935c41 and installed kernel 6.3.6 like you suggested and tried booting it but I had the same issue. First boot is motherboard vendor screen followed by black, subsequent boot is motherboard vendor screen followed by GRUB followed by black screen after choosing which kernel to boot. This time I was able to enter my LUKS password, give it a minute, switch to ALT CTRL F3 and log in as root and then reboot. So again it seems like everything is running except the video output.
On which kernels do you have this result? Please check both 6.2.15 and 6.3.6 (since you can still login with terminal at 6.3.6, right?). Is this a permanent state at each boot? If so, write a short note to the bug report that cat /proc/sys/kernel/tainted remains permanently at 512 (and on which kernels it does that).
It would be indicative if such a value also exists on 6.2.15.
Supplement: Assuming that at least 6.3.6 has the 512 return, I assume the origin is:
Jun 07 20:00:02 desktop kernel: ACPI Warning: SystemIO range 0x0000000000000B00-0x0000000000000B08 conflicts with OpRegion 0x0000000000000B00-0x0000000000000B0F (\GSA1.SMBI) (20221020/utaddress-204)
Jun 07 20:00:02 desktop kernel: ACPI: OSL: Resource conflict; ACPI support missing from driver?
If 6.3.6 returns 512, feel free to add these lines as well to the bug report together with the short note mentioned above, just to provide some overview of the existing kernel warning.
Of course it would be interesting to know if that also exists on 6.2.15 (just like its tainted condition)
@bluepixels feel free to check on your machine if things are comparable.
I misunderstood you. I thought you could still use the terminal. However, we have the result
It seems your 6.2.15 kernel also has some issue, even if it seems to work. It would be interesting to know what this is, and if there could be a link (although I assume the answer is no if your 6.3.6 returns 0).
This means, is the output always the same, even in between boots. So, reboot, and check again. If the output of the 6.2.15 kernel remains 512, it would be good to have also the output of journalctl -k while you run 6.2.15 (so to get the 6.2.15 kernel logs).
So, just reboot, select 6.2.15, check the cat /proc/sys/kernel/tainted command, and if its value is still 512, then directly/immediately get the output of journalctl -k. Since 6.3.6 returns 0, I think this is something different. But just to be sure, I would have a short look on it. Then we can decide if it makes sense to add this to the bug report.
I just ran cat /proc/sys/kernel/tainted on 6.2.15 and it returned 0 this time. This is a different boot instance to the last time I ran the command since I booted into 6.3.6 to get the last taint report.
Yeah it didn’t ask me for dmesg, I will reboot into 6.3.6 and get the output of dmesg and report back with the attachment.
EDIT: The taint for 6.3.6 is still 0 and I will attach the output of dmesg into the bug report. The taint for 6.2.15 for this boot is 0 as well.
EDIT 2: @py0xc3 Something I forgot to mention is I have a KVM switch for Display Port 1.2 standard. All of these tests so far have been via the KVM switch. I can run this again without the KVM switch if necessary.
If this was a one time issue, then let’s skip it for now. If it does not cause issues and if it is no permanent phenomenon, it was likely only a single occurrence that made the kernel for once triggering a warning. This can be sometimes caused just by plugging something in that the kernel does not like (and where it becomes active to mitigate some behavior or so).
Good to have the dmesg there. Thanks. I hope the kernel report template is back in place soon, but I guess this will be fixed soon.
Well, behavior/issues in the kernel can have many outreaches/impacts within/outside the kernel. This is one reason why finding bugs in an operating system kernel is such a tricky task. I have seen freezes that occurred when the screen was turned on, and the origin was the WiFi driver
I think it is unlikely that this is the origin, but since this is not a widespread combination while you are currently the only user experiencing this issue on F37, I think it is worth a try. You have to know that screens are today actively interacting with the kernel and no longer just “passive receivers” of data. So things that are related to data transfers within HDMI/DP can be indeed related to such issues.
So, remove the KVM switch when the machine is off. And then once boot 6.3.6 and see if it makes a difference.
Can you boot once with 6.3.6 and with the additional parameter module_blacklist=ucsi_acpi ?
E.g., you can in the grub menu go to 6.3.6 and click on “E”. Then there is one line that begins with “options”. Go to the end of this line and add there module_blacklist=ucsi_acpi (of course with a space before). Then do CTRL+X to boot with this parameter.
No. It begins with options. For example: options root=UUID=<UUID> ro rootflags=subvol=root rd.luks.uuid=luks-<UUID> rhgb quiet amd_pstate=active module_blacklist=ucsi_acpi → that’s from a system
that normally blacklists a network driver, which I changed to ucsi_acpi.
Whatever text the users have before the blacklisting, they only need to
append the blacklisting parameter to the end of the line. Everything
else shall remain as it is in their file (the above is only an example).
This looks like this installation has not been reinstalled from scratch
for long, or strongly customized. I haven’t seen something like that for
long. That could have been default when all entries were consolidated in
one grub file, but I think that was changed already several years ago
(don’t exactly remember how it looked like back then).
title Fedora Linux (6.3.5-200.fc38.x86_64) 38 (KDE Plasma)
options root=UUID=<UUID> ro rootflags=subvol=root rhgb quiet
This is default as set from Fedora (more precisely, Anaconda) today in
one of my installations; I just replaced the UUID. And this is not KDE
If your installation is very old, it might be relevant to note that this
is the whole content of one entry file as stored in /boot/loader/entries
→ this has not always been the case that way, but I think this default
has been set already several years ago (but don’t remember exactly when
You can check the config files for grub in /etc/ (with which it creates
new entry files) in current installations, which by default add
parameter through “options” (the wiki page above also elaborates that
Another explanation for your case could be if you used the network
installer or another installer that is shipped with blank/unaligned
configs (network installer does not come with the aligned configuration
as determined by Fedora’s WGs/SIGs). I don’t know how these configs look
like if installed with that.
Once again I have to disagree. I have a VM that was installed new about a week ago with fedora 38 using the default first release ISO for F38, and the entry from pressing “e” at the grub menu shows this.
Unless the entries for KDE are significantly different than workstation our grub menus show radically differing content from the screen during boot.
It may be you are giving content from a different file or location, but the grub menu clearly does not show an “Options” line for a standard clean install on Workstation.
I also only have the default /etc/default/grub and the default entries in /etc/grub.d
However, within the file located at /boot/loader/entries/UUID-6.3.6-200.fc38.x86_64.conf I do see the content as you show. That file is not accessible for edit from the grub menu during boot, and that content seems created when running grub2-mkconfig to recreate the grub.cfg file.
The “linux” line from the grub menu seems a combination of the “linux” line and the “options” line in the matching .conf file under /boot/loader/entries.
