We're now three weeks away from the official release date of the Steam Deck handheld Linux gaming machine. The good news is that Verified titles have been growing nicely!
Still nothing compared to the overall Steam library but we do fully expect a lot more titles to appear. This is just the beginning and not being verified doesn't mean a game won't work.
https://www.gamingonlinux.com/2022/02/over-120-titles-are-now-steam-deck-verified/This is only those titles fully Verified too as there's also now 111 titles that are marked as Playable like Factorio, RimWorld, The Witcher 3, Deep Rock Galactic, Valheim, Morrowind, Path of Exile and the list goes on. Some of the reasons being text too small, manual graphics settings adjustments needed, launchers, spotty gamepad support and so on. We expect many of the Playable titles to improve or even get Verified before the Steam Deck launches.
Só se for no Ubuntu. Em Arch o GNOME 42 é estável e fiável.Instalei recentemente o Ubuntu 22.04, e deveria ter esperado. GNOME 42 muito glitchy...
The LXQt team announces the release of LXQt 1.1.0, the Lightweight Qt Desktop Environment.
Earlier this month marked the launch of the HP Dev One as an interesting collaboration between HP and System76 for a laptop optimized for Linux developers and running System76's Ubuntu-based Pop!_OS operating system.
At $1099 USD, the HP Dev One is powered by an AMD Ryzen 7 PRO 5850U 8-core/16-thread processor with Radeon Vega graphics, 16GB of DDR4-3200 memory, a 1TB NVMe M.2 2280 SSD, and a 1080p 14-inch 1000 nit display. The specs are great and the Ryzen 7 PRO 5850U SoC is a wonderful choice for this mid-range to higher-end developer-minded laptop.
The laptop measures in at 32.3 x 21.4 x 1.91 cm and weighs 3.24 lbs / 1.47 kg. The HP Dev One features an HP Long Life 3-cell, 53 Wh Li-ion battery.
In total I ran 87 benchmarks across all of these laptops under test with Pop!_OS 22.04. All the individual data and benchmarks can be found via this OpenBenchmarking.org result page.
here are benchmarks of the HP Dev One while trying out Arch Linux, Ubuntu 22.04, Fedora Workstation 36, openSUSE Tumbleweed, and Clear Linux in addition to the default Pop!_OS 22.04 installation.
https://www.phoronix.com/scan.php?page=article&item=hp-devone-linux&num=1Lastly is a look at the geometric mean of all the benchmarks carried out where they successfully completed on all operating systems under test. Obviously just the raw performance is being looked at and not the power/thermal results here. Pop!_OS 22.04 was right inline with the performance provided by openSUSE, Fedora Workstation, and Ubuntu 22.04 on the AMD Ryzen 7 PRO 5850U powered HP Dev One. Arch Linux in its default configuration from Archinstall was noticeably slower than the rest. Intel's Clear Linux meanwhile offered around 13% better performance overall than the other Linux distributions thanks to its aggressive default performance tuning, extra patches, and other optimizations.
El portátil ThinkPad Z13 hace uso del procesador AMD Ryzen PRO 6860Z, el cual integra el coprocesador Microsoft Pluton. La gama de productos Ryzen PRO se enfoca a empresas y profesionales cuya información almacenada es valiosa. Agregan medidas de seguridad adicionales para evitar posibles robos de información.
Esto es positivo, hasta que se han detectado que debido a Pluton, no se puede instalar Linux en un portátil. Claro, esto lleva a una pregunta, ¿puede Microsoft decidir que instalo en mi ordenador?
Aparte de la polémica en torno a la ejecución de Linux en los portátiles ThinkPad Z13 y ThinkPad Z16, queda la carta de “coger el hacha” e inhabilitar Secure Boot de raíz. Eso debería de eliminar la barrera que impide el inicio de sistemas operativos alternativos, pero a saber cuáles son las consecuencias en esos equipos con el coprocesador Microsoft Pluton en medio, porque el proceso de comprobación de firmas ya no debería de estar presente, pero es posible que Linux siga sin arrancar por culpa de una incompatibilidad de hardware.
Cuidado, porque se empieza con Linux y…Muy posiblemente que no se pueda instalar una distribución Linux te dé verdaderamente igual, y con razón. Pero, esto es un precedente que se podría extender hacia otro software más generalista. Imagínate no poder instalar Google Chrome, Firefox o Brave, que Microsoft te obliga a usar solamente Edge.
Vamos más allá. Podría darse el caso que Microsoft llegue a un acuerdo con Adobe y que solo puedas usar Photoshop en tu equipo con Windows, no usar las alternativas. Que solo puedas usar Microsoft Office y no OpenOffice, por ejemplo. Seguro que se te ocurren más alternativas.
Esto también podría terminar con la libertad de instalar mods en juegos o simplemente, bajártelos para probarlos y decidir si lo quieres comprar. Al final, Microsoft con la bandera de la seguridad está limitando que puedes hacer en tu ordenador personal. Podría empezar a imponer restricciones que impidan acceder a software o incluso, a páginas web.
Matthew Garrett discovered that Linux wouldn't boot by default on the new Lenovo ThinkPad Z13 due to it by default not trusting bootloaders/drivers signed with the Microsoft 3rd Party UEFI CA Key. He wrote on his blog, "This means that given the default firmware configuration, nothing other than Windows will boot. It also means that you won't be able to boot from any third-party external peripherals that are plugged in via Thunderbolt. There's no security benefit to this. If you want security here you're paying attention to the values measured into the TPM, and thanks to Microsoft's own specification for measurements made into PCR 7, switching from booting Windows to booting something signed with the 3rd party signing key will change the measurements and invalidate any sealed secrets. It's trivial to detect this. Distrusting the 3rd party CA by default doesn't improve security, it just makes it harder for users to boot alternative operating systems."
https://www.phoronix.com/scan.php?page=news_item&px=Lenovo-Pluton-Windows-DefaultThe restriction to only Windows by default is rather silly but at least it sounds like it still can be disabled from within the UEFI BIOS to allowing alternative operating systems to boot. Hopefully Lenovo changes this though as indeed a rather silly move to see from them and their Linux support that had been increasing in recent times.
Eu já lí uma noticia ontem no telegram que de certa forma desculpava a Lenovo, porque e também segundo eu sei quem gere as assinaturas em processadores é a própria Microsoft, de certa foram desculpa a Lenovo e a própria AMD porque eles produzem mas quem gere a assinatura UEFI é a Microsoft.Era para ter colocado ontem, estava a tentar entender o porquê da Lenovo estar debaixo de fogo...
Meteram a pata na poça, foi o que foi!
New Lenovo AMD Laptops With Pluton Co-Processor Reportedly Only Boot Windows By Default
Vem configurado dessa forma "por padrão", mas aparentemente pode ser alterado na UEFI, mas tendo em conta as iniciativas da Lenovo no campo OSS, atraiu bastante atenção, NEGATIVA.
Mas actualmente e recorrendo aos APU AMD a estrela parece estar a ser mesmo o HP Dev One, que creio ainda está apenas acessível nos USA.
The modern look is powered by 12th Gen Intel® Core™ 28W processors (up from 15W on the prior generation) and supported by larger fans that provide 55% better airflow without increasing noise or temperature.

Here is the first of several articles looking at the AMD Ryzen 7 PRO 6850U Linux performance using a Lenovo ThinkPad X13 Gen3.
The Ryzen 7 PRO 6850U is 8 cores / 16 threads like the prior Cezanne Ryzen 7 PRO 5850U but now with a 2.7GHz base clock and 4.7GHz maximum boost clock compared to 1.9GHz base clock and 4.4GHz boost clock with the prior generation part. The Ryzen 7 PRO 6850U has a 15 to 28 Watt configurable TDP and this Zen 3+ processor is manufactured on a TSMC 6nm FinFET process compared to TSMC 7nm FinFET with the former Cezanne Zen 3 models.
The Ryzen 7 PRO 6850U also now supports DDR4-4800 / LPDDR5-6400 memory compared to DDR4/LPDDR4 with the Cezanne models. Arguably most exciting with the Ryzen 7 PRO 6850U is the Radeon 680M graphics that are based on RDNA2 rather than the long used Radeon Vega graphics with prior AMD APUs.
My Ryzen 7 PRO 6850U Linux testing has been happening using a Lenovo ThinkPad X13 Gen3 (21CM0001US) that features 16GB of LPDDR5-6400 (soldered) memory, 512GB NVMe PCIe 4.0 SSD, 13.3-inch 1920 x 1200 IPS 300 nit display, and makes use of the integrated Radeon 680M graphics. It's a nice laptop and all basic functionality works out under Linux while more on the laptop itself under Linux will be talked about in the forthcoming ThinkPad X13 Gen 3 Linux review.
The laptops/processors used for this initial round of AMD Rembrandt Linux benchmarking included:
- Core i7 8565U - Dell XPS 13 9380
- Core i7 1065G7 - Dell XPS 13 7390
- Core i7 1185G7 - Dell XPS 13 9310
- Core i7 1280P - MSI MS-14C6
- Core i7 1280P - MSI MS-14C6 + 5.19-rc7
- Ryzen 7 4700U - Lenovo LNVNB161216
- Ryzen 5 5500U - TUXEDO Aura 15 Gen2
- Ryzen 7 PRO 5850U - HP Dev One
- Ryzen 9 5900HX - ASUS G513QY
- Ryzen 7 PRO 6850U - ThinkPad X13 Gen3
- Ryzen 7 PRO 6850U - ThinkPad X13 Gen3 + 5.19-rc7
All of these laptops were tested on Ubuntu 22.04 LTS using the Linux 5.18 kernel.
Due to seeing improved power efficiency for Alder Lake P with Linux 5.19, the Core i7 1280P was tested both using Linux 5.18 like the other laptops and again with Linux 5.19-rc7. So, similarly, the Ryzen 7 PRO 6850U was tested also with Linux 5.18 and 5.19-rc7.
Across both OpenGL and Vulkan workloads the Radeon 680M graphics were performing very well on the latest open-source drivers. For those interested in the Radeon 680M potential for Linux gaming, a follow-up article will look much more closely at the 680M gaming performance...
It's with the CPU power consumption where the Ryzen 7 PRO 6850U becomes much more compelling. Above is a look at the CPU power consumption over the entire span of benchmarks conducted. The Ryzen 7 PRO 6850U with the Linux 5.18 kernel had a 18.4 Watt average (or 16.6 Watt average with Linux 5.19 Git) while the Ryzen 7 PRO 5850U average on Linux 5.18 was up at 21.96 Watts. The peak power consumption of the 5850U during testing was 47 Watts compared to 41 Watts with the 6850U or even down to 35 Watts with Linux 5.19 Meanwhile the Core i7 1280P had a 35 Watt average on Linux 5.18 and a peak of 107 Watts... It's with Linux 5.19 Git where the Intel Idle driver support is there that Alder Lake looks better in the power efficiency department but still behind the Zen 3/3+ parts tested. On Linux 5.19 the i7-1280P had a 30 Watt average and a peak of 75 Watts.
https://www.phoronix.com/scan.php?page=article&item=amd-ryzen7-6850u&num=1The Ryzen 7 PRO 6850U CPU core temperature in the ThinkPad X13 Gen3 during the entire span of benchmarks was 69 degrees compared to the 5850U having an average of 81 degrees. The Core i7 1280P in the MSI Evo notebook had an average core temperature of about 67 degrees.
The AMD Ryzen 7 PRO 6850U in most benchmarks was only slightly faster than the Ryzen 7 PRO 5850U, but its power efficiency with Zen 3+ tended to be much better. It was a nice improvement in performance-per-Watt with Rembrandt and further extends the AMD power efficiency wins over Intel Alder Lake P.
