  1. Cinnamon and Xinerama

    Thanks Oleg! // Erik
  2. Cinnamon and Xinerama

    Hi, As mentioned in another post I am a bit tired of KDE at the moment and have been struggling some time with the, as it seems, impossible task of configuring Cinnamon. I have had all kind of problems mostly based in the fact that cinnamon turned out to use my three displays as one single display. After some searching I found out that I was missing the xinerama USE-flag. This is default on KDE and I have verified that xinarama is enabled on a lot of packages using the kde-plasma-5 mix-in. If I use the cinnerama mix-in the xinerama USE-flag will not be automatically set but have to be set in make.conf Is this a cautious decision or an mistake? Shall I write a feature/bug request? Regards, Erik
  3. Funtoo on atom

    Hi Enrique, I have had Funtoo (and Gentoo) installed on my EeeeeeePC 2014 (or similar), atom CPU and I managed to install 2GB of ram. It works fine for anything but web-browsing as modern web sites makes have use of JavaScript and that virtually kills the tiny CPU. To be frank, the installation of Funtoo and XFCE takes like forever. Several days of compiling. Make sure that the power is connected and to make sure the ventilation works well. If the compilation phase, well, is alive (produces output) it is ongoing. The Guide is generally good and normally works well but it takes quite a while even on a modern desktop computer. It is worth waiting for :) If you have a another and more powerful computer also running Intel CPU you can make the compilation on that. There is a trick mentioned in another post here. It is not a step-by-step description but a description for experienced users, sorry for that and I don't have anything better at hand right now. It is the part about all the details to find out CPU-settings that might need a bit of digging, but once the CPU settings are determined it is fairly straight forward. One thing to mention is that you should probably build the kernel on the actual computer you will use, I have had strange stuff happen otherwise and it makes sense - kernel does not adhere to the /etc/portage/make.conf -file as it is not a portage build. It is worth mention that Funtoo is a very nice operating system on the old computers once installed. Runs well, slimmed, openRC does not start a lot of crap just in case, etc etc. I am generally very satisfied with the result (except for the Java-script web-sites then). The 10.3" laptop is the only thing that actually fits on a airplane and have been a very good travel companion.
  4. I think this was crap in the settings. Started a new user and managed to add stuff as expected. Case closed for now :)
  5. Funtoo on a laptop best practices

    Hi, I have been using Funtoo on my laptop for quite a while, also for my professional laptop in my own business. First of I am extremely satisfied with OpenRC, it works well and if one need to verify the started services there is a list of about 25 while SystemD starts subservies and crap and produces a list that is impossible to review. I also find that openrc have the support I need to restart services easy when I am on work and need to be professional bnut I figure that is a matter of what one is used to. Many laptops have Intel CPUs and built in graphics. This works well mostly out of the box (debian sources). Like Palica I don't use hibernation but I think it might work. I suspend to RAM and are very satisfied. I use KDE and have configured the power settings to ignore the fact I close the lid and I have to press the power button that I configured for sleep mode. This way I can save battery by closing the lid and thereby the screen. For network I am using Network Manager and it works quite well. Need to be restarted once in a while after many sleeps and it is easy enough with openRC. Wifi and stuff works well but one need to install sys-kernel/linux-firmware to get all the drivers going. I also have a initramfs as I am using BTRFS as root on an encrypted disk. There is one trick I am using though. The laptops is not nearly as powerful as the desktop computer is. All of them are Intel. I sometimes share the / partition and mount it on the desktop, and then I mount a local filesystem on the working directory for portage. The I emerge all my stuff (chromium, libreoffice, firefox all takes quite long time). One need to be careful with the CPU-flags in /etc/portage/make.conf though. Same princiles as is documented for DistCC. Checkout the Gentoo Wiki and the section for CFLAGS and CXXFLAGS, the compiling device will report wrong CPU-flags unless exactly the same CPU. I connect both computer to Ethernet LAN, not WiFi, when doing this trick. It works like a charm but is a bit cumbersome to setup each time. Beside the usage of NetworkManager I am not doing any thing particular installation wise for the laptop but once I made some power management extras. It was a log time ago but I recall Gentoo have a very nice wiki page to that part. // Erik
  6. I am also not a friend of Akonadi that seems to have been problematic since it was introduced. When I develop something I always strive to use standard and simple storage that can be understood without my fancy application. Plain text files or well formatted JSON is my favourite :)
  7. I am a long time KDE user but have a growing feeling that it is time to look into another desktop environment. I have been around since KDE 3 and every time they refactor I think they lose something. KDE 3 was superior. I am no friend of Gnome 3 and fails to get cinnamon working with 3 monitors in different sizes. Right now I am updating my XFCE installation and will try out Gnome Evolution as the next step. I realize that despite how much I enjoy developing in Qt most of my programs are using GTK (Firefox, Inkscape, Libreoofice etc etc) and I might as well be able to adjust the settings properly. Most likely I will make a go for Mate as well, just as a test :) I thought of Thunderbird but I always considered it a bit clumsy so for now it is plan B. Naturally I'd like to establish mail and contacts using Dav-clients to sync between my different units. I use this for my business and need to be in sync. Cheers, Erik
  8. Hi, I upgraded to kde-kit 5.12 and also installed KDEPIM. There was an obstacle where I needed to remove mysql and install mariadb instead but that seemed to work fine. Once installed I can add mail accounts and it seems to work well. Problem is that when I add calendar or address books from my Dav server or OpenExchange (have both) the guide works out, I can find the resources but the result is not added to the list. I restarted akonadi in a shell to get printouts but nothing in particular there. I started Kontact in a shell to get printouts but nothing there either. What is my next step? I have cleared akonadi directory when it failed to work so there shall be no db migration problem I think. I think of trying out Evolution but there is no address book syn for dav or open exchange. Other options to replace Outlook is few. Regards, Erik
  9. ZFS Mountpoints

    Hi, I have been using btrfs on my rootfs for quite a while and one of the ways I am using it is that I always do upgrades in a snapshot of root and when upgrade is done I use that as new root. In btrfs this is very simple. I have my root in /mnt/btrfs/root I make the snapshot as /mnt/btrfs/root-upgrade, I chroot into this an perform the upgrade. When I am done I simple rename the dirs; mv root root-fallback mv root-upgrade root Nothing is changes on my system and as mount with -o subvol=root applies to the subvolume named root at the specific point in time when mount runs I will simply enter the upgraded system. Question is; can I do something similar in zfs? Is there a way to make zfs use another name or mountpoint next time I boot but not directly? Regards, Erik
  10. Over time I have experienced problem that my keyboard does not work during early boot, the time where I am supposed to make key-map selection on system-rescue-cd, but - more important - at the time I am expected to enter encryption key to unlock my encrypted partitions. If I end up in rescue mode I can't do anything, not even ctrl-alt-delete to reboot. I have had the problem on my current and previous hardware if I am using debian-sources (4.8 and 4.14). I have this problem with all kernels I have tested with my present hardware (ASUS Prime Z370). Naturally it failes with my ordinary logitech k750 keyboard but it also fails with a ordinary plain USB cable connected USB-keyboard. I have played around with different settings in kernel (gentoo-sources) to build in or not support for USB, logitech modules, the fundamental USB HIDBP, etc and cannot observe any difference during boot (but I managed to disable mouse in KDE). I can see that the logitech modules are loaded when booting debian-kernel but it still wont work. This is the latest dmesg where HID is loaded [ 1.239301] hidraw: raw HID events driver (C) Jiri Kosina [ 1.239542] usbcore: registered new interface driver usbhid [ 1.239780] usbhid: USB HID core driver . . .

I use the very same and slightly modified linuxrc and initrd.scripts. Modification is an own luks open function that is similar but independent from the cryptroot-stuff. Instead I open encrypted partitions specified at kernel line in specified order right before BTRFS scan is performed. Eventually I might send a patch. I have tried the solution mentioned in https://forums.gentoo.org/viewtopic-t-1063372.html but it didn't work.
  11. Well, thanks for the help in this thread. I started to test combinations of my 4 memory modules and found out that something is wrong and it is possible that there is a problem with the motherboard. I have moved on to greener pastures and are now installing on my brand new I7-8700K setup instead. It is fabulous. After I managed to boot on debian-sources I also had to rebuild webkit-gtk that would actually freeze the computer after 20 minutes. That is what I used to test the memory modules. Eventually I will return to that motherboard and try to find the problem, it is intended to be a server taking backups. If I decide to trust it. Regards, Erik
  12. I managed to boot with UEFI and debian-sources. All 16GB of memory are there but keyboard wont work during boot so I cannot enter password for encrypted disks, thus the time delay. Seems like I have some miss-configuration in my kernel config but on the other hand it has been around for some time and are based on the one for my previous hardware that is based on the hardware before that.
  13. EFI boot with linux mint and ubuntu/kubuntu seems to work and I have all the memory. Still not booted into debian-sources.
  14. I am using crucial, forgot the exact module right now. I am not overclocking. I did build the PC my self. I have suspected memory problems at some stage (some 6 month ago) and tested to remove them in pair. I think they are purchased as a set of 4x4 modules. There is a lot of BIOS settings, any particular of interest, and I have tried quite some combinations. I have verified the problem in UEFI Only mode as well as combined Legacy/UEFI. UEFI only mode used my DIsplayPort as main output while legacy enabled uses the DVI-port. I (think) I have disabled secure boot, it is only used when instaƶlling kubuntu and is disabled directly when the nvidia drivers is installed so there is little point. I am currently installing debian-sources but that will take quite some hours so I know more later tonight :) // Erik
  15. I forgot to mention; I am booting the very same linux root and home partitions from BOIS and EFI, using the very same kernel-file and initramfs-file and get different results. 16GB if I boot using BOIS and 4 if I boot using EFI.
