Ubuntu 20.04 is out
« on: April 18, 2020, 04:24:41 pm »
Canonical has released Ubuntu 20.04 beta on 16th. It should be the same to the final version, rest of minor bug fixed. Software version and kernel version are frozen, and the rest I can't imagine to be too far off.

I'm glad to report that it runs near-perfectly on ThinkPad X1 Gen 7 with 10th-gen Intel CPU.

Rest of fingerprint sensor and LTE, all peripherals work, including Thunderbolt 3 and beam forming microphone array, which were didn't work quite well in previous versions.

I'm also surprised to find my 10GbE AQC107 NIC works out of the box, so far I've not seen much of an issue.

There are issues related to Thunderbolt 3, namely partial device enumeration, but I take that it is a use land bug as devices can show up, just not working properly. Replugging in devices solve the problem without needing to modprobe.

HiPDI support is wonderful, way better than Windows, which is the reason I tried it in the first place. KiCAD and LibreOffice look much more natural than on Windows, and are significantly faster.

Media-rich web pages suffer from performance hit more than on Windows, which is the only performance hit I've encountered now.

Youtube and Gmail random color bad pixel bug (introduced to 4K ThinkPads from Win10 1910 to current) doesn't seem to affect Ubuntu.

what version does simply 'python' give you, and what does 'python3' give?
this 2-to-3 transition is a bit of a mess IMO...

Oooh wonder if the installer shits a brick on virtualbox still... there goes the rest of my evening  :-DD

Just been QA'ing CentOS 8 to replace my current CentOS 7 builds so may not bother. CentOS 8 is pretty damn solid.

Ah yes I need conservative releases here. Worth looking at Fedora. That's closer to Arch end of things.

One thing I like about the RHEL/Fedora/CentOS ecosystem is it's nuclear bomb proof.

I don't regard beta as "out" lol.

Not for my machine for actual work. I'll upgrade from 18.04LTS when the software updater suggests it to me around July or so...

Can't fault 18.04 yet, nor desire to battle with a beta  :scared:

..like many still do with Win 10 in 2020  :D

Not sure how the Mac battlers are doing with their current Mountain climbing/falling OS,
gave up on that infinite upgrade joke ages ago  ::)

That's certainly true with RHEL and CentOS (and Oracle Linux, which is pretty much RHEL as well), but Fedora is the experimental branch of the Red Hat family and can be hit and miss sometimes.

What I can recommend is openSUSE. It's as reliable as CentOS (the current openSUSE Leap 15 is based on SuSE Enterprise Linux 15), and thanks to YAST it's probably the most user-friendly Linux distribution that exists.

SuSE is the #2 vendor after RH for the Enterprise market. We use SELS (SuSE Enterprise Linux Server) and SELD (SuSe Enterprise Linux Desktop) in various applications, as well as the free variant openSUSE where support isn't needed.

The final version of 20.02.0 LTS will come out in a week. If I'm to wait for 20.04.1, I might as well wait for 20.10, and it goes on forever.

Hardly.

I don't upgrade anything -- not my Mac, not my iPhone, not my Linux machines -- until a few million people have been running that version for a month or two, not just a few thousand.

I run bleeding edge versions of the software I understand intimately and am an active developer of. It's crazy to do that with everything else.

This is not at all the same thing as waiting forever.

It is with Linux at least. So much trouble on new hardware. On windows you can usually limp it along until you get the drivers in.

This is one reason I'm running a Ryzen desktop with windows and all my Linux stuff is in VMs.

I use opensuse for many years, at work and at home, currently Leap 15.1.
I tried some other distro's and/or desktops in the past but I always come back to opensuse with plasma/kde desktop.

If necessary (rare) I run windows in virtualbox. No way I'll ever do it the other way around.
I'm so used to it that I'll probably never work again in bigger companies where some boss tells me what to use on my pc.
I'm too much used to my freedom now and the improved workflow that comes with it.

At least update your kernel to the most modern one you can get, the default kernel is really old, and the newer ones, while not by default upgraded, are a lot better. I got the latest available, 4.4.0-98-generic, though I really should do a full backup to a drive, then format fully, and install a newer LTS version. At least I do not really have to reinstall /home, as it is on another drive, though I suspect I will have to dig out the encryption keys for it for the new version. But doable, and there are even utilities to slowly find it when you upgrade.

QFT, experienced the nightmare as I was Linux total noob, when I got my new 1st gen Ryzen, which was just 6 months after released by AMD. Installed latest stable Fedora at that time, everything went fine for 1st round of installation, and then it prompted me to update as it detected newly system, followed the suggestion and installed it right away, and boom, booted with tons of error and left me clueless in command prompt.

Some of that was probably systemd being a prick :)  :-DD

I have to do a lot of windows and .Net stuff as well so I still need a windows base system. Although I got a triple head T470 dock setup working here the other day. Literally just plonk the laptop in the dock and gain two more screens. I can't imagine the hell I'd have to go through to get that working properly on Linux.

Yes. I've never been this happy to lose such a big chunk of money.

Is KiCAD has reached AD level?  ???

U-turn after 4 years?  :o

After getting most of my commonly used apps installed and run properly, and Windows installed inside VBox, I nuked the native Windows and reclaimed its partitions.

So far Ubuntu has yet to fail me, at least not this time.



Classic 'famous last words' in computing land   :-BROKE

FULL IMAGE the lot NOW, twice to two external drives/storage, while it's running great..

..you're welcome   :)

Far away, but good enough for basic routing. It lacks a lot of advanced tools like bundle routing (xSignals and the new batch follow me, for instance). But if you are not after automation (which is what I do all the time), manually dragging tracks is not that different between them.
That shit is a meme, you use it to quickly cobble together a rubbish pile of a design when you are doing work for an employer. The fab may have a 3mil minimum clearance but that doesn't mean I want to put traces exactly 3mil apart everywhere possible. I hate push and shove routing and anything that behaves like it. I would *never* use the routing follow mode because I never want traces "as close as allowed" to anything. Space allocation is always based on a variety of factors that overall optimize for manufacturability followed by performance. When I lay out a board, I already know in my mind exactly where on the board each trace will go and the only job of the tool is to let me draw what I want as easily as possible. Anything else is simply a gimmick feature and are only useful if I want to wing it and get shit over with.

I have been running 20.04 for about a month on a few VMs (VmWare Workstation 15.5 Pro) and it looks quite alright in basic compatibility for our software.

On real hardware the chances of success vary greatly - the trouble I had with 18.04 (and probably on 20.04) was with Wi-Fi support on an older Dell Latitude 6520 - I had to use wired LAN to get the appropriate support. Apart from that, the more recent versions of Ubuntu tend to be mature enough to get the work going alright.

(in older versions pre-12 or 10, it used to be quite hard to make all the hardware dependencies on home-built PCs to work well)

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...

LTspice works fine under wine. I keep a windows VM around for the occasional use of sending files to taobao vendors (mechanical drawings etc). I think I've booted up the windows VM maybe 3 times in the past year lol.

I can, technically install some sort of phone companion, and use WeChat on my phone, then use the companion to shuffle files back and forth over WiFi, but before I find one that works perfectly, I still need my computer to have Windows running in a VM, though I really want to nuke it as well.
Connect your phone to the computer over USB. MTP sucks ass but for transferring the occasional file it usually works fine. When it doesn't, I use "primitive ftpd" from f-droid which supports sftp (use sshfs to connect).

Ubuntu is still missing drivers for fingerprint sensor (now working with source version, should get it pushed to apt soon) and LTE (experimental drivers available from GitHub, should merge in 5.8 or 5.10 kernel).
Or you could just put a few layers of masking tape over the fingerprint sensor like everyone else does ;)

Laptop with built in LTE sounds like the best idea ever /s. As if the baseband processor being integrated into phones and having DMA access isn't bad enough.

Thunderbolt fails to enumerate all devices if plugged in before booting, and so far my solution is to plug it after booting into desktop.
Thunder what? What do you need that for?

Dude, I'm typing this on an old HP laptop, 1366x768 screen. It might not look new and shiny but it has 4 (!!!!!) USB ports, an actual ethernet (!!!) port, a dedicated DC jack (!!!), a headphone port (!!!), and a full size HDMI port should you need to use an external display. The small screen size doesn't hinder my PCB design work at all and I've never needed an external display. I guess you need the high DPI display to see all your moon runes in their glory detail. New laptops with only a single USB C port can suck my anime girl cock.

With a bit of help from winecfg and winetricks as well as some scripts I found from CSDN and GitHub plus some extensions from Gnome extension store, I was able to get LTSpice to WeChat to run perfectly natively on Ubuntu.

Maybe Windows is not needed after all, I wonder.

The CNC software, CNC proprietary CAD and Altium all went to my scope, and now my portable system is Windows-free.

I'm also glad to report the Thunderbolt bug is fixed in 5.6 OEM kernel Canonical built for Dell XPS, it works fine on X1 too.

I did some media creation/consumption test, and it seems like Rhymebox works fine with most music formats, and it reads/writes to my 8-year-old iPod Nano Gen 6 well. I still need some time to get used to it from iTunes, but it will happen.

Kdenlive works almost out of the box, with additional plasma desktop needed for dark theme. OBS works fine natively with no frame drops at 4k->1080p real time recording.

After tweaking some parameters with lenovo-throttlefix and careful application of liquid metal thermal interface material, no frame drop is observed during watching YouTube video while blasting the CPU with full workload.

It also allows the CPU to run cooler at no more than 92C (so no thermal throttling before power throttling) even when SIMD is used at mac load (OBS and Kdenlive, for instance).

Screen ghosting (reversible burn-in) remains, as it seems to be a hardware design issue of the BOE panel. To bad that this panel has vivid and accurate color, pitch dark black, blinding brightness and practically no IPS glow and bleeding.

I first thought it was an OLED, and unfortunately, it also has the dreaded ghosting OLED has -- just it is reversible. And yes, I did gently press it with a blunt tip, and it indeed is NOT an OLED. It is very insensitive to pressure, but it is not completely impervious to pressure, unlike an OLED.
Just a question. Have you ever considered PopOS? MX linux is my go-to distro for old(er) hardware but I've recently switched to PopOS (and W10 :-/) and many things work out-of-the-box. System 76, who's behind this, also manufactures (builds) laptops so it is somehow tweaked for new hardware. I recently purchased P1 G2 and hybrid graphics is the biggest hassle.

A note: Many stable distros (like MX linux) rely on the old 4.19 Kernel because it simply works. There are many quirks with 5.x kernel.
