Linux Mint Forums

Thanks for the info JeremyB. I am currently running 5.16.10-051610-generic which seems to also have solved the problem.
I am able to boot with both monitors attached and the graphics hardware is enabled.

Thanks for the clarification.

As far as I can tell this patch has the fix for dual monitors cause system to hang on boot with Intel RocketLake-S GT1 [UHD Graphics 750] (rev 04). Workaround is to disconnect one monitor, boot then plug in second monitor. The patch "[PATCH 5.16 092/203] drm/i915: Workaround broken BIOS DBUF co...

Thanks for all the followup.
Let's close this thread and wait until the official 5.11 replacement comes out. I think you said this would be sometime in the April 2022 time-frame.

I have an external USB drive that normally boots up as /dev/sde. For some reason in the pastebin log for the 5.11 kernel it got mounted as /dev/sda. That pushed all the other drive letters down. 5.11 -> 5.16 sde -> sda sda -> sdb sdb -> sdc sdc -> sdd sdd -> sde Is that ok? Otherwise I can boot into...

Logs from the 5.14 kernel.

I do not know if that relates at all to the issue at hand, but the log indicated you have the prior version, 2.02. So I have installed 5.16 generic, just because it is easy to install using TuxInvader PPA. I noticed when I installed 5.16 during the update-initramfs command it complained about "...

SMG your are fantastic!! I very much appreciate you not giving up on this problem. So your research proved to be excellent. System booted fine with 5.14-oem kernel with one monitor attached. The ASUS Prime Z590-A has 2 video ports. One "DisplayPort" and one HDMI Port. It did not matter whi...

ok here it is:
journalctl -b -1 | nc termbin.com 9999

I do not know how fast your computer normally is to get to the login screen (or the desktop if you automatically log in), but give it that much time before you kill the power and then boot with the 5.11 kernel so you can go get the log info from the "black screen" boot. System usually boo...

Is it out now?

Yes.

I need to see the error messages of when the system is NOT working. And there is the problem. I cannot get any kernel to boot (other than those mentioned below) so therefore we cannot see any error messages. Do you normally see grub when you boot? Are you not seeing grub and that is why you are tel...

anticipating your next question: uname -r 5.11.0-46-generic journalctl -b | grep -i "drm\|i915" Jan 23 12:54:26 sys76 kernel: fb0: switching to inteldrmfb from EFI VGA Jan 23 12:54:26 sys76 kernel: i915 0000:00:02.0: vgaarb: deactivate vga console Jan 23 12:54:26 sys76 kernel: i915 0000:00...

Understood. OK this is what I know: Kernel 5.4.0-96 boots ok, but only in software rendering mode. Kernel 5.11.0-46 boots ok and works in HARDWARE rendering mode. This is the kernel that I currently use. (Unsupported as of next month) Any other kernel I have tried, including 5.14.0120-oem fails to b...

Most 95 CDs are NOT BOOTABLE. If a download does not include a boot floppy, please see Microsoft Windows Boot Disks.

While I am awaiting any further replies, I think I will try the Edge version of Mint 20.3.

ok - 5.4.0-96-generic boots normally into software rendering mode so here is the output from the commands. $ uname -r 5.4.0-96-generic $ journalctl -b | grep -i "drm\|i915" Jan 22 22:18:55 sys76 kernel: ata2.00: supports DRM functions and may not be fully accessible Jan 22 22:18:55 sys76 k...

5.14.0-1020-oem would only boot in recovery mode. Output of commands shown below. Trying to boot 5.14.0-1020-oem normally results is a hang at BIOS boot logo screen. $ uname -r 5.14.0-1020-oem $ journalctl -b | grep -i "drm\|i915" Jan 22 21:50:31 sys76 kernel: ata2.00: supports DRM functio...

I have not kept good documentation on exactly what I have tried. Most all version of the kernels available through Update Manager plus linux-oem-20.04d.

I am willing to (re)try any kernel recommendations you might suggest and any additional troubleshooting procedures as well.

Has anyone been successful getting the Intel RocketLake-S GT1 [UHD Graphics 750] chipset working on MintLinux 20.?. I have it working on kernel 5.11.0-46-generic x86_64 using a recommendation from this forum. But support for that kernel ends next month. I have googled for a solution but nothing I ha...
