Excalibur's questions

A friend of mine gave me his old laptop. HP Probook 470. Only the harddrive was missing so I used an old one I had lying around. Installed windows 10, may update, on one part of the drive and Ubuntu 20.04.1 LTS on the other part. However, after install, the machine did not want to boot back to Windows. I tried the tool Bootrepair (the log it created for forum support is located at: https://paste.ubuntu.com/p/tM5GWZHN8H/ ) and I tried the Windows 10 boot repair option via booting from the USB install disc. That one came up empty completely. Bootrepair tried something but did not fix it the way I would like it to boot. It shows the grub2 bootmenu and it boots to Ubuntu just fine, it also shows the listing of Windows 10 but when I try to boot to it, it just stays silent/black for a bit and then returns me to the GRUB2 boot screen. Or maybe it reboots and brings me back to the GRUB2 boot screen.

I'll be using Ubuntu mostly, luckily. It just is a joy and gives me some new stuff to learn, I was a bit done with Windows. Not that I know everything of course but getting the hang of Ubuntu, at least the basics and be grounded solidly in it, is something I'd like to build up.

Anyway, anyone that can help me out? I would like to keep the GRUB2 bootloader appear and then have me choose for an Ubuntu or Windows 10 boot.

Usually I fiddle about a bit more myself but since I am on a very very slow internet connection, I'd to ruin one of the installs by fiddling about too much and having to wait 4 hours to download all updates again during or after install of Ubuntu/Windows combined. Combined it took eight hours today, so... any help is greatly appreciated!

Fastboot in BIOS is off. SecureBoot is off also. The custom.cfg file as per suggested topic did not change anything. I ran bootinfoscript as also suggested in that topic and pasted the results here: https://pastebin.com/AqBFZCY1 Still more info can be found in the log Bootrepair created, which I have posted here: https://paste.ubuntu.com/p/tM5GWZHN8H/

The command sudo efibootmgr -v churns out:

BootCurrent: 0000

EDIT: I messed up the install below due to n00b and trying bleachbit and updating, probably not rebooting in between had that effect. Could fix most of it but didn't feel right. SO I moved to a clean install of 19.10. System has 6GB of ram, install chose, again, to allocate too little swapspace (still only 2GB, compared to 1GB in the previous install) HOWEVER in 19.10 physical RAM doesn't fill up nearly as fast and the swapspace that is being used is around 500MB after 10 hours of use while the 19.04 version would fill up both after an hour orso of use. Had to reboot after 3 hours. So, at least to me, it would seem that memory management in 19.10 has improved, or that there is something wrong in the 19.04 version. I still allocated 6GB of memory, just to be sure. Running conky I get to monitor stuff and I think this is the way Linux is supposed to function. So should I not be the only one out there with this problem on Disco Dingo, try moving to a newer version.

System does what I stated in the problem desc. I have been trying to find out what goes wrong where and via "glances" and "iotop" it has led me to this problem description. The swap and ram fills up, is able to stay at around 99% for a period of time (most often it takes a couple of hours before the system becomes unresponsive) and then iowait just goes through the roof. The moment that happens, hdd led starts burning full and disk read/writes of most, if not all, processes are shown to be anywhere from 0 to tens of MB/s in iotop. Which doesn't get the time to update anymore, nor does glances. The only thing that then works is a hard reset. I need to do this multiple times a day and is making my linux experience horrible.

The best I could find over the last couple of weeks was this problem description from someone who has been experiencing the same problem as I am experiencing on my laptop. https://unix.stackexchange.com/questions/373312/oom-killer-doesnt-work-properly-leads-to-a-frozen-os

This is a serious problem which more people, even very experienced ones, far more than me, seem to encounter quite a bit. Yet, no one seems to know where to turn to. To verify the above, please consult the link above and its links and comments.

Anyone? Any tips or advice? Somewhere to turn to perhaps?

Here are my systems' specs and output which I'll list for completeness. However, I am unsure if this will be of any benefit. If any other data is necessary, please provide me with the required commands and I will execute them gladly.

I have searched far and wide, yet I am confronted in GNOME on 19.04 with the fact that I cannot get umlauts etc to work. I have 2 kali (KDE) machines, on which I can get it to work quite easily. However, in this case, under Settings - devices - typing column - to find the "compose" key - is not there... I've edited etc/default/console-setup to include XKBOPTIONS="compose:Shift+AltGr" but I am sort of afraid to reboot, in fear that I might break something. Also it does not seem like the correct way since setting this functionality has been standard on previous versions of ubuntu etc.

This question has been asked many times, and has been solved many times, which is how I solved the umlaut problem on Kali/KDE too (since I am quite new on linux). Have tried linux many times in the past but only now it sticks. Any problems I have had up to now I have been able to solve without asking but this one is beyond me.

Am going to reboot now anyway, I guess I will have to.

If I don't return shortly, something broke. Otherwise, I'll be back soon ;-)

Thanks!

returned, system did not break aaannndd.... trying... e No joy. Pressing the AltGr key just shows the firefox menu bar.

I'm lost.
