FurretUberHi, what is the correct way to do something as "sudo apt purge linux*generic*" now?01:52
FurretUberAs globs seem to no longer work on apt01:57
Bashing-omFurretUber: Cleaner way ' sudo apt --purge autoremove ' - will leave the current kernel and one other.02:18
FurretUberThe example I took from a case where an user had to install the lowlatency kernel but it was not possible to open the grub menu (this I don't know why)02:19
FurretUberSo after confirming linux-lowlatency was installed, that command was used to remove the generic kernel as grub was the generic kernel02:20
FurretUberBut using globs on 20.04 apt is no longer possible02:20
FurretUberUsing the same example: https://paste.ubuntu.com/p/bSrdDBt8Jy/02:22
FurretUberI imagine this change will cause some programs to break, and I would like to be aware what would be the 20.04 equivalent02:22
FurretUberGlobbing not working on apt will break at least one of my image creation scripts02:29
lotuspsychjegood morning02:54
AlexMaxI'm having issues with the graphical installer05:03
AlexMaxIt seems super-desparate to tell me about how it's going to create "Primary" and "Logical" partitions despite booting into EFI mode05:04
AlexMaxAlso, it seems super-desparate to tell me that it's going to format a swap partition located on a completely different hard drive that I would prefer the installer not even touch05:04
AlexMaxAlso it mentions boot loaders - which I thought wasn't a thing on EFI05:05
AlexMaxAt least the wiki page about EFI notes that I really shouldn't be seeing that selection in EFI mode05:05

Dr8g0nHey all - I installed 20.04 yesterday on HP 360. All very very well. Except for multi-touch gestures on touch screen (these on touchpad work).08:43
Dr8g0nAnybody knows how to fix?08:43
lotuspsychjeDr8g0n: mostly when i tweak system, i try dconf-editor but i dont see much about touch or gestures, maybe you can look around too?08:45
lotuspsychjeDr8g0n: an other approach for touchscreen devices, is installing unity desktop and test things there too, they usualy have great touch support08:45
Dr8g0nlotuspshychje thanks but I do like Gnome too much... Looking for a solution on 3.36...08:47
Dr8g0nlotuspsychje ... (getting to grips with IRC again as well - it's been over a decade I think)08:48
lotuspsychjeDr8g0n: yeah i understand08:48
lotuspsychjei havent touched gnome much yet on touch devices yet, think it might still have rough edges08:49

freezerwhere can i find a newer firmware?09:54
tomreynyou could potentially find newer firmware in the "linux-firmware" git repository, but there doesn't seem to be any. also this is not the very latest hardware so normally it should be working out of the box. i guess it's something specific to this kernel version. then.09:56

freezeryou have any IGP, maybe its displaying it on that?10:10
tomreynfreezer: i wouldn't expect nvidia (proprietary) drivers to work with non default kernel versions, no.10:18
tomreyn(that's in response to "would kernel 5.6 still work with the nvidia drivers?")10:18
pavlushkatomreyn: the version is 5.4 on 20.04 and the card works with the 440 driver on a 5.5 kernel on arch10:21
tomreynthose driveres are versioned, too, and usually further customized by the distribution shipping them. unless you using drivers you downloaded from nvidia.com, which would not likely work on ubuntu anyways.10:27

howarthWhat actually happens is that the Apple HD Cinema display (under nvidia drivers) will light up its LED back into sleep mode indicating that it has lost contact with the graphics card13:40
howarthI tried 44013:40
howarthThat was enough for me13:41
howarthIt is exactly the same issue as always13:41

howarthI'll give that a spin on my test external drive that I have been using for testing the full installs13:47
lotuspsychjeits worth a test right howarth 13:47
lotuspsychjeolder card, test the oldest driver13:47
howarthStill will be a rough ride if I want to use Wayland13:47
howarthThe freeze is actually pretty random13:47
lotuspsychjehowarth: nvidia + wayland is not perfect yet13:48
howarthI'll leave my main drive with nouveau/wayland to see if that suppresses it.13:48
lotuspsychjethere are some improvements and workarounds out there, but think still being worked on13:48
howarthAnyway, it probably won't be long before the GTX680 is dropped out of the main nvidia releases13:49
howarthI am still trying to puzzle out the situation with clock scaling and nouveau13:50
howarthI thought there was supposed to be code added for that at some point13:51
howarthIMHO, other than the nvidia issue, a 2008 MacPro is pretty much the sweet spot for running linux on a Mac13:53

MikeRLThis may be the wrong place to ask, but I heard and experienced hellfire trying to get 19.10 on the Pi 4. I tried an unofficial image someone brewed up and it works. Source is from: https://jamesachambers.com/raspberry-pi-4-ubuntu-server-desktop-18-04-3-image-unofficial/14:39
ubukingHere is only 20.04 support!!!!!! 😳 14:40
MikeRLNo issues. How difficult in short would it be for someone, if interested, to get 20.04 with the desktop on the Pi 4? 18.04 is better than no Ubuntu, as I dislike Raspbian in comparison, and the server variant works well, but the GUI is a mess on the offical images.14:40
MikeRLYeah I know. Just mentioning that if 19.10 didn't play nice chances are 20.04 will be harder as well.14:41
MikeRLNot too much excessive changes from a release prior to an LTS to an LTS.14:41
MikeRLI donate per each Ubuntu release, but after realizing there's a shortage of manpower and time as the main bottlenecks, I don't throw as much money at the Pi releases.14:43

FurretUberHi, I'm having a problem with the new APT. I'm reading the man page but now hit a problem16:43
FurretUberOn 18.04, "apt list gc*7*" would show all packages that start with "gc" and have a "7" in the package name16:44
FurretUberAs this no longer works on 20.04, I'm trying to use the patterns. However, "apt list '~ngc ~n7'" find anything that has "gc" and "7", regardless if it starts with "gc" or not. Even worse, it is finding pakages with the "7" before the "gc"16:45
FurretUberSo, what is the 20.04 equivalent for "apt list gc*7*"?16:46
ducasseit's working here17:05
FurretUberWith list it works, but it doesn't on install or purge17:08
FurretUberWhen I gave a real example with purge yesterday, the focus was given on why I would use that command instead...17:12
FurretUber...and the reason is that I don't know how to make the default kernel be a non-generic kernel17:13
FurretUberBut this specific question is about apt patterns on 20.0417:13
ducassetry escaping the *17:16
FurretUberIt didn't work, the error message is exactly equal, however17:23
