[02:25] <ArgentinaTango> Hi
[02:25] <ArgentinaTango> I install an Ubuntu Studio to make my phd thesis
[02:26] <ArgentinaTango> But in the start have a lot of problem with video
[02:26] <ArgentinaTango> Can someone help me?
[02:28] <n4dir> I probably won't be able to help, but for others to help you should probably tell your graphics chipset (if i understand your problem correct)
[02:28] <n4dir> lspci -k  | grep -A3 -i VGA
[02:28] <n4dir> i think
[02:30] <ArgentinaTango> Where i see the model?
[02:31] <n4dir> the first line. You could just do "lspci | grep -i VGA".
[02:31] <ArgentinaTango> Maybe Gforce 210
[02:31] <n4dir> -k will add the driver in use, which is the last line. But, bad news, i am not in such problems. (mainly intel over here)
[02:32] <n4dir> if i am not wrong this time this channel isn't outstanding active. So if in doubt ask at another time. Good luck
[02:32] <ArgentinaTango> gt218 nvidia corporation (gforce 210)
[07:35] <bastien> OvenWerks: Thank you for your advice. I'm going to look for an application to see CPU activity, that's a good idea. Concerning my AMD, the "governor" is in "performance" mode, and the "boost" option is not available. In the bios, I disabled a "quiet&cool" option, but I just saw a "Core performance boost" option that I might need to disable. The low latency core is well installed.
[07:36] <bastien> OvenWerks: Have you made some of your settings in your motherboard bios, too? Maybe I'm looking in the wrong place :)
[07:39] <bastien> I could only try all this out tonight: I'm at work right now :(.
[09:19] <MauroGaspari[m]> [bastien](https://matrix.to/#/@freenode_bastien:matrix.org) in my experience,  the hardware interface quality and how you set it up, is what makes the biggest difference with xruns. When i plug a good audio interface to my systems (I have both amd and intel), no cpu tweaks make a real difference.   If you are sure you previously used the same interface in another computer, it might be worth checking what changed
[09:19] <MauroGaspari[m]> in the new one in terms of interface drivers, or usb power/drivers, or see if there are any important firmware updates for your interface.
[09:19] <MauroGaspari[m]> Also try to search the net if the interface you are using has reported driver bugs or regressions. What I am trying to say,  try to broaden you troubleshooting instead of focusing on one thing too much. I hope it helps.
[11:27] <bastien> MauroGaspari[m]: thanks. Indeed, all the tests I have made (tweaks processor) have very little influence and do not solve the problem. In fact, the only thing that changes is the computer: it is much more recent. The audio interface is the same (I moved it), and my old computer was also running on the same version of ubuntu studio. So, I might look at the "usb power/drivers" side, I don't know if there
[11:27] <bastien> are any tools to help me (apart from testing all the usb ports). It is a scarlett 2i2 3rd gen interface.
[11:32] <MauroGaspari[m]> bastien: I don't have that one but I remember of people in the linux community reporting some minor issues and fixes. I will try to see if I can find those posts and get back to you
[11:36] <bastien> MauroGaspari[m]: thanks. The audio interface works well, apart from the fact that I find my latency too high compared to the computer I have (higher than on my old computer).
[11:58] <MauroGaspari[m]> for my USB interface, this is how I have Jack Master Settings. For me switching sample rate to 48000 and jack periods to 3 helped quite a bit.

[11:59] <bastien> MauroGaspari[m]: it is my actual config, excepting buffer size set to 512 to avoid xrun
[11:59] <bastien> (and it is big buffer size comparing the computer : ryzen 3400g and 16Go)
[11:59] <MauroGaspari[m]> bastien: woah 512 on a scarlett seems way too high.
[12:00] <bastien> MauroGaspari[m]: yes ! that's why i asked lot of question her :(
[12:00] <bastien> *here
[12:14]  * MauroGaspari[m] sent a long message:  < https://matrix.org/_matrix/media/r0/download/matrix.org/EOuZuHurBQqpXWxeHHsqBAHN/message.txt >
[12:22] <bastien> MauroGaspari[m]: OK, I'm at work right now and I don't have the computer in front of me, but : 1 - Yes, Real time permissions is enabled. 2 - uname -a said i use a lowlatency kernel (which i have installed). 3- No power saving software is installed, my ubuntu install is quite fresh :). 4 - Bios was updated, I will look the usb port settings, but i don't touch it, it's the factory default. 5 - I will do
[12:22] <bastien> the full power off, and 6 : i try different usb port, but not all usb port (same problem), i will.
[12:24] <bastien> In any case thank you for these ideas, I'll try it tonight when I get home and give you the result (for the full poweroff and the usb ports)
[12:24] <bastien> To precise the 4, i try all USB2.0 port on the motherboard. The other are USB3, but i will try these too.
[12:25] <bastien> (scarlett 2i2 has usb2 connection)
[12:25] <MauroGaspari[m]> bastien: I wish you a good day and good luck with JACK!
[12:26] <bastien> Thanks :)
[16:38] <OvenWerks> bastien: my i5 does not have hyperthreading so I don't have to turn it off. I was able to do so when I was running an older P4. But even there the only difference it made was with latency of 64/2 and lower. I was able to get my PCI audio down to 16/2. USB will never get that low as the transfer rate is 1ms (16/3 at 48000) and in such a case you need to double that for reliability. So 32/3 is about
[16:38] <OvenWerks> minimum. Also, it makes a difference which physical USB plug one uses.
[16:41] <OvenWerks> A lot of the newer motherboards internally route all the USB 1/2 ports to one bus and one irq.
[16:41] <OvenWerks> this means your mouse ends up being at the same priority as your audio IF :P
[16:43] <OvenWerks> it is almost best to install a USB PCIe card to use just for the audio IF and make it's IRQ a higher priority and the MB USB a lower priority.
[16:45] <OvenWerks> In my case I was able to turn the MB USB3.0 stuff off so now the USB is split into two parts with the ehci (USB2) driver. One for front and one for rear)
[19:11] <Maik> Eickmeyer: ping
[19:12] <Eickmeyer[m]> Maik: Pong? (standby)
[19:13] <Maik> Eickmeyer[m]: maybe it's better i take my question offtopic since it's not Studio support related
[19:13] <Eickmeyer[m]> Maik: Sure
[19:13] <Maik> i forgot you guys had a offtopic channel too
[22:18] <citadel__> Hi, Audacity breaks my audio (studio 20.04) https://pastebin.com/pyMN40Aa
[23:57] <Eickmeyer[m]> citadel__: Like I told you elsewhere, you have a weird plugin from kxstudio likely. Some sort of incompatibility.
[23:57] <Eickmeyer[m]> !kxstudio | citadel__
[23:59] <Eickmeyer[m]> Long-story short, we can't support systems that have added that repo here as it creates a franken-Buntu.
