[gentoo-user] Corrupted font in gtk apps.
Hi, after recent update I encountered a problem with fonts. They looks ugly and somehow corrupted. I see that in gtk apps I use, but maybe it is also in other apps. I encountered it on two computers, both amd64. Before a week it was fine. I use gentoo stable. I have fixed it partly by using Terminus font in all places where I can. But this is only workaround. All other fonts (bitstream 75bpp, dejavu) are corrupted. I also logged a bug https://bugs.gentoo.org/show_bug.cgi?id=400909 I hope I'm not the only one who has this behavior. Regards, Robert
Re: [gentoo-user] Video Out on laptop

Re: [gentoo-user] Video Out on laptop
So to enable external output you can do this: xrandr --output VGA-0 --auto --output LVDS --off to switch back xrandr --output VGA-0 --off --output LVDS --auto you can assign this to some shortcuts. Or do a acpi script for the hotkey. I have done similar for docking and undocking on my thinkpad. Also you can use the tools for your DE, for example krandrtray for KDE or gnome it has in Settings I think. Robert.

Re: [gentoo-user] Re: Corrupted font in gtk apps.
It is wired, because I use KDE and qt apps are ok. I can change the font for gtk but some are displayed wrong. I have tried to play with fontconfig but did not help at all. I have also check the xorg.log and fount that there are included only /usr/share/fonts/100dpi 75dpi and misc. Nothing more. But I see the other fonts like DejaVu in gtk-chtheme or the kde gtk settup. So I think it is not a problem of xorg font loading. And is wired that it happen just week ago, and I did not change any config since that, only do a regular merge of stable updates. Regards, Robert.

I don't have that problem now but when I've seen it in the past it was because Xorg wasn't finding all of the installed fonts for some reason. There may be easier ways to diagnose the problem but I always use the very old x11-apps/xfontsel, which at least will let you know for sure which fonts Xorg is actually seeing, if not the reason for the problem.
Re: [gentoo-user] Re: Corrupted font in gtk apps.
Thanks for your help, I have found the problem. After checking my homedir I observed I have accidently uncommented some old xft stuff in .Xdefaults file. That cause the problem. Robert.

This is not saying that gentoo is bad, I'm very big fan of gentoo. But you have to concern where it use and where not. Robert. Anecdotal, but... I once had an Ubuntu VM that can't shutdown after a kernel update. First boot after update went well, but when I rebooted it again, it pegged its vCPUs at 100% before I ordered the Xen hypervisor to put it out of its misery. I don't want to start flame, but ubuntu was never a system for server for me. It may be good for desktop, but not server. For me ubuntu is too up-to-date to be a good server distro, even the LTS is not something well done, maybe in version x.x.3-4 of LTS it s reasonable to put on server, but it will soon end with support. So nothing for me. The bug was apparently in the portion of the kernel running in the primary CPU that's responsible for shutting down the other CPUs before cutting the power. And IIRC, this bug affects all multi-processor configuration. So, as you can see, binary distros can still fuck up royal time. Not to mention that if you have an exotic configuration, support for your configuration might not be built into the kernel by the distro. This is true, but you cannot compare countless options that gentoo can be configured with few options that binary distro is capable and thus more probably tested before. Somehow I believe people deploying Gentoo servers will be much more careful... Agree. But real word is not so ideal. I got situations where I need upgrade basic gentoo server to more special virtualized environment. Just a customer wanted that. This consist about changing net to bridge, add/update kernel modules, etc. I ended with bricked server after a long checks etc, so I have to check the server physicaly. I did another thing in debian remotely within a half hour. This also implies that I'm not so good admin, but things happen not so good as you expect every time. I still use gentoo on my notebook and work computer, or specialized project where it benefits. But all the servers are migrated to debian or centos. I just don't have so much time to play. Robert.

I've followed all of the wiki entry at http://wiki.gentoo.org/wiki/DisplayLink, but there's something else I need to know. I get the green screen on the TV that it mentions when the kernel module is being loaded correctly. The problem is that I use gdm in /etc/conf.d/xdm DISPLAYMANAGER variable to start X, and I don't know where the actual gdm configuration lives so I can tell it to use ~/.xinitrc2 from the wiki. My google searching hasn't been going well. Can anybody give me any hints as to how to make progress on this problem? Hi Michael, it depends on how you would like to use the external card. Please specify your scenario. Anyway, try to look in /etc/gdm, /etc/init.d/xdm, /etc/X11 (there can be specified which server start in file xdm/Xservers) I have DL adapter connected to my docking station and a simple script to activate the second xserver on docking and deactivate that when undocking. I simply run here second desktop using x2x. I just use that primary for web browser, so I dont need xinerama. You can also use DL with your primary card and xinerama. But it needs specific xorg.conf and needs to be connected when xserver starting. So nothing suitable for notebook and hotplug. Robert.
Re: [gentoo-user] Tips for saving power needed...
Hi, maybe write your hw configuration first. Eg: CPUs, graphic cards, HDDs (size, speed, type) and others. Also provide lspci output and /proc/cpuinfo. Then this is a server, maybe with more than one GB nic. If you dont use spare nics disable them in bios. Do the same with other unneeded stuff. If you can access your server and replace cards, remove everything you dont need. Do not lower fans or dont play with cpu voltage. If you want to run this server 24/7 it can cause serious problems. It will not save you much power. Paradoxly this could lead to higher power usage in some cases, because of hotter devices. Remove spare memory cards, if you dont need much memory, etc. Robert.

The driver is loaded, wpa_supplicant and wicd get to recognize them, I can see the association working correctly, but I can't get the card to authenticate, it ALWAYS times out. I tried looking at the kernel documentation for the ath9k driver, but without success. I'll look for it using the work internet. Anyway, does anyone with a similar setup had any problems with atheros nics? And how did you solve it? Thinking further, I had to enable wireless extensions (wext) to make wicd handle ath9k. Should I disable it and stick to wpa_supplicant? Also, I'm using a non-modular kernel, compiling everything in it. Yesterday I left the notebook making a new modular kernel, with sound and wireless drivers modular. I'm almost going all the way to genkernel. Any clues? I'm running ~amd64, kernel 3.3.0. 3.1.X worked somewhat ok, but I can't shake the feeling that under Windows this laptop of mine would work flawlessly.

Re: [gentoo-user] Anyone setup Gentoo on an Archos 101
Nice project. I dont know this tablet, but I have similar project that want to realize when time will arrive. I have Asus eee note, nice grayscale tablet with wacom digitizer. I want to make some guide and build environment to prepare image for that. If you want to install gentoo there, I suggest you collect as much information about the hardware, how and where kernel can be placed. Create virtual environment to build the image (qemu). Also get as much information how are the possibilities to debug and recover, if something goes wrong. Robert.

Re: [gentoo-user] System cold crashing when too much memory is used?
Hi,
what rebooted Dom0 or DomU? Have you some special need to run kernel 3.4.9,
try 3.0.35, I dont have any issue on server with 3.0.x.
Other thing, try to disable swap and run the script. Could be disk problem or
bus/controller problem when copying pages from swap.
Robert.

I always think about in such cases if I really need such data. In many cases with clear consideration I find out I may remove half of the data without any pain.

In any of my data arrays I have long time migrated off the RAIDZ to the MIRROR or RAID10. You will find finally that the RAIDZ is slow and not very flexible. Only think you gain is the extra space in constrained array spaces. For RAID10 it is much easier to raise the size, just resilvering to new bigger disks, removing old and expanding. The resilvering speed is magnitude faster. And anyway much easier to recover in cases of failure. If you really need the additional space, consider adding second jbod with another disks. Robert.

Corrupt the data, and you'll be tearing your > hair out why things go wrong randomly, with no automated way, even once > you've realised what's happened, to recover your data other than a > restore from backup. Yes I'm sure. What I meant easier is that the pool is much easier to handle and recover. For RAIDZ1 the thing you mention for MIRROR is the same, only it is multiplied with the amount of disks. So if 1 disk fail and you resilver, then all the remaining disks spinning to populate the spare. If any of them fails, then you are screwed. RAIDZ2 is better in this space and in case of 4 disks it is better when it comes to resiliency (for 10 disks it may not be true), but you lose the flexibility. Also time to resilver under RAIDZ is much slower, which means longer time under unprotected pool. It is always needed to decide what workload you are serving and how precious the data are. For data like movies RAIDZ1 is enough I think. Also it is good to check the SMART data time to time to see the amount of error corrections (some are ok, but highly rising no). Solaris has FMA for this to kick in spare. Under home environment it is fine to check it time to time and consider new disk before the old one completely dies. This reminds me I need to buy new disk to my home NAS :) (because of the rising corrections). And finally, always do backups for the data you are about to save. I got raspberry pi with attached USB JBOD with two disks serving as backup station. It is not fast to be a real NAS, but to do send/receive of incremental snapshots it is enough. I automaticly sync there the datasets that are worth not to lose (photos, documents, etc), many times these datasets are also the ones that are not such big. Ideally put this backup station to some remote location (or at least different room).

Re: [gentoo-user] rescue cd for zfs 2.1 or thereabouts
Hi John,
my approach is to have EFI partition with staticly compiled grub, alpine
linux rescue system and kernel with tiny initramfs for zfs root.
It works really well, only thing you need to consider is when upgrading
root pool, you will not be able to boot to previous BE with old zfs.
Without upgrading the pool, the transition is just easy as recompiling
new kernel and upgrading the zfs userspace tools.
For the alpine I use script to put a new version on /boot
https://github.com/robertek/root-scripts/blob/master/alpine_recovery_update
and having grub entry:
menuentry "Alpine linux recovery" {
linux /boot/vmlinuz-lts modules=loop,squashfs,sd-mod,nvme quiet
nomodeset
initrd /boot/initramfs-lts
}
The alpine extended version contains zfs modules, so you only need to
"apk add zfs" and then modprobe zfs.
The extended version is little bit bigger, but I'm fine to live with 1G efi
partition.

Re: [gentoo-user] How to degrade Gentoo system with webrsync method?
Hi, to the downgrade thing it can be partly done using the squashfs portage snapshots laying on every portage mirror. There is a long history list there. https://gentoo.osuosl.org/snapshots/squashfs/ So you can migrate your portage tree from plain files to the squashfs. But actually the real issue here is that you are modifying your live system with potentially broken things and than stay in a non working state. For stable binary distribution there is a very high probability that upgrade will pass correctly. But on gentoo the probability is much less. So it needs to be counted with. The easiest thing is to let the portage create binary packages from the ones that are unmerged and keep old portage squashfs at hand. This is still live system and I would not do that. Instead just use any filesystem for the root that allows you creating boot environments (zfs, btrfs, lvm). I have only experience with zfs, so creating boot environments is very easy and an atomic operation, where the upgrade only happen in a new BE until it is ready to go. Having BE setup correctly and squashfs images in it, provides you a consistent working environment all the time. And if something does not work as expected, you may return to the previous BE (if you didnt remove it). Robert.

The last time when it failed to recompile was on 30-12-2021. I reported this in the thread "tensorflow-2.5.0-r1 compilation failed" So, I decided to degrade my Gentoo system to the state in which it was on 12-12-2021, when my tensorflow was still ok, and froze it forever. The problem is that I do not know how to sync my Gentoo repository to the state it was on 12-12-2021. I use webrsync sync method via "maint -A sync" and would prefer to use the same sync method for degrading my Gentoo system. Can anybody, please, tell me how to do it using this sync method?
