ALWAYS install firmware on WIN11, download from Dell, click on it from explorer. Had re-updated firmware from ubuntu on 24-03-25 as offered by snap, Mipi works, LC display works only because boot installed new UEFI, equivalent to passing thorough UEFI (mistery!). However at a second try cannot boot (stops with two lines of EFI and a blinking central light on the keyboard). All well after win11 BIOS update.
apparently cannot boot with HDD connected to hub
fn-ESC toggles lock on fn or audio/light/stamp/.../canc
reflashed latest UEFI from WIN11, BitLocher is permanently removed, so directly download from Dell with the product key (self identified) and simply launch, waiting for completion.
- had previously updated firmware from linux
attaching SSD to hub is enough to fail the hdmi recognition, see SsdBoot
hdmi sees hdmi again after booting in Win11, which does detect HDMI. Now works also after suspend, resume in 6.5 (with no Mipi drivers). Now also works in 6.11, with Mipi and suspend.
- but after a long suspend hdmi does not come back! and touchpad misbehaves... Maybe must go through BIOS to reactivate detect. Working xrandr_output.
MIPICamera: ultimate recipe, remove and install again intel-ipu6-dkms if kernel has changed
restore vpn forticlient, occasionally upgraded to non free version: sudo apt remove forticlient sudo dpkg -i Downloads/forticlient_vpn_7.4.0.1636_amd64.deb
sleep drains battery, hibernate does not work, see https://bugzilla.kernel.org/show_bug.cgi?id=215367#c2: disable Early DELL logo in BIOS, to enable deep sleep (uspend). Seems to work
- hibernate not working, following https://feriman.com/enable-hibernate-on-ubuntu-2404-easily-step-by-step-instructions ).
- moved swap to a 40GB partition compressing win 11 to 180 GB with gparted (first mount/umount /dev/nvme0n1p3 to check win is off)
- modify grub sudo vim /etc/default/grub and to implement sudo update-grub
- Install https://extensions.gnome.org/extension/755/hibernate-status-button/ to get hibernate buttons in power applet.
- use either sudo systemctl hibernate or applet power button hibernate. It hibernates regularly, however, it does not resume. See e.g. log/hibernate-resume.2025-02-14T00.08.log
- enabled AHCI on windows, by Restart, run (Win Key+R) => type msconfig.exe and choose => boot => safe boot. On the reboot, hit F2 or Delete and go into Bios ( before Safe Mode ) and change to AHCI/RAID as needed. Then boot into Safemode and let Win10 load the default MS drivers automatically. This nis expected to reduce battery drainage in suspend mode, but does not shopbut it does not (from 100% to 55% after 16 hours!)

- extract several qpdf multipage-file.pdf --pages . 1-5 -- pages1-5.pdf, or 3,5,11-14@, reverse order @z-1@, last two pages r2-r1@@
- multiple source files place qpdf file first.pdf pages=1-4 second.pdf pages=r4-r1 merged.pdf
- qpdf multipage.pdf --replace-input --pages=r3-r1 overwrites with only last 3 pages
- use --collate=i,j,k,... to take i from the first, then j from the second, then k from the third, then i from the first, etc.
