Report: Linux Cannot Be Installed on Microsoft Signature Edition PCs, Laptops and Tablets

Microsoft Signature program is designed to make sure certified devices offer the best possible experience for users, as they can not come with bloatware, include Windows Defender, and must meet strict hardware requirements. However according to a Phoronix report, “providing the best possible user experience” also includes blocking installation of alternative operating systems such as Ubuntu, Debian, or other Linux distributions. The issue was discovered by rijesh who attempted to install Ubuntu 16.04 on his Microsoft Signature Edition Lenovo Yoga 900 13-ISK2 laptop, and noticed that while the BIOS and Windows 10 could see his 512 GB hard drive, Ubuntu was unable to find it, and a customer support representative answered that: This system has a Signature Edition of Windows 10 Home installed. It is locked per our agreement with Microsoft. Another user reports having successfully installed Ubuntu 16.04 on his Lenovo YOGA 900-13ISK, so the devil is in the […]

$35 expEYES Junior Transforms the Raspberry Pi, Aakash2 Tablet or any Linux Powered Device into an Electronics Lab

I remember in high school in France, our class only had 2 oscilloscopes and few other electronics equipment, needless to say I did not actually get to use an oscilloscope until I went to university. It would have been nice to be able to play around with oscilloscopes, frequency generators, etc… earlier, but due to budget constraints, this was not possible. Dr Ajith Kumar, a scientist working with the Inter University Accelerator Centre of India, has spent several years working on an ultra low cost electronics lab composed of an oscilloscope and a signal generator to provide students attending schools that cannot afford regular equipments. This learning & experimentation tool is called expEYES, and a prototype was demonstrated last year with the Raspberry Pi. At the end of last year, the final version called expEYES Junior (aka expEYES 2.0) was announced, and is now available to schools and hobbyists in […]

2D/3D Graphics Linux Demo (X11, EGL, GLES2, Qt4) on AllWinner A10 Tablet

Xlab (Maxim Kouprianov) has tested 2D & 3D capabilities of AllWinner A10 SoC (with Mali-400 GPU) on a Ployer MOMO11 Bird Edition tablet running OpenEmbedded with kernel 3.0.52+ testing X11, EGL, OpenGL ES2 and Qt4 on the platform, and the results are pretty smooth as you can see in the video below, although there appears to be some flickering in LunaSysMgr demo. The tools used in the demos are xfwm4 (Xfce Windows Manager), es2gears_x11, cube (Qt), LunaSysMgr (Qt/WebOS) and glmark2-es2. Qt4 acceleration is done via XlibGL platform which in turns uses X11-EGL. He used the Mali drivers version r3p0 (mali400-gles20-gles11-linux-x11-ump) and xf86-video-mali on sunxi-linux github repository mainly maintained by rz2k. You can get more details on how to build Mali-400 support for AllWinner A10 on http://linux-sunxi.org/Mali400, and GPU benchmark results for A10 show the drivers seem to work as expected.

Kamvas Pro 16 (2.5K) review – A 15.8-inch drawing tablet and stylus with 8192 levels of pressure sensitivity

HUION Kamvas Pro 16 (2.5K) is a 15.8-inch drawing tablet with 2.5K resolution that comes with a stylus supporting 8192 levels of pressure. The company sent us a review sample, so I’ll test it as an external display in Windows 11 and Ubuntu 22.04, and check the drawing functions of the Kamvas Pro 16 with the stylus as well as other potential use cases. Kamvas Pro 16 (2.5K) specifications (model GT1602) But before that, let’s list the specifications of the display: Panel – 15.8-inch (diagonal) IPS display at 60 Hz Resolution – 2560 x 1440 (16:9) QHD PPI (Pixels Per Inch) – 186 Active Area – 349.6 x 196.7 mm Contrast Ratio – 1200:1 Brightness – 220nit (Max.) Response Time – 14ms Viewing Angle – 178° (89°/89°(H)/89°/89°(V) (Typ.)(CR＞10)) Color Gamut Volume – 145% sRGB Color Gamut Coverage – 99% sRGB / 99% Adobe RGB Colors – 16.7M (8-bit) Surface Finish […]

Linux 6.8 release – Notable changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.8 on the Linux kernel mailing list: So it took a bit longer for the commit counts to come down this release than I tend to prefer, but a lot of that seemed to be about various selftest updates (networking in particular) rather than any actual real sign of problems. And the last two weeks have been pretty quiet, so I feel there’s no real reason to delay 6.8. We always have some straggling work, and we’ll end up having some of it pushed to stable rather than hold up the new code. Nothing worrisome enough to keep the regular release schedule from happening. As usual, the shortlog below is just for the last week since rc7, the overall changes in 6.8 are obviously much much bigger. This is not the historically big release that 6.7 was – we seem to […]

Rockchip roadmap reveals RK3576 and RK3506 IoT processors, Linux 6.1 SDK

The Rockchip RK3588 processor may remain the most powerful processor from the company for a while as an updated Rockchip IoT processor roadmap reveals the new RK3576 octa-core SoC and RK3506 tri-core Cortex-A7 chip, as well as a Linux 6.1 SDK to be released in Q4 2023. With the limited information we have, the Rockchip RK3576 looks to be a cost-down version of the RK3588 processor with eight cores, a 6 TOPS NPU, a 4K video codec, as well as PCIe and USB-C interfaces. Strangely the Rockchip RK3582 that should serve a similar purpose is not showing up in the roadmap. [Update: The RK3576 is indeed a lower-cost SoC but features four Cortex-A72 and four Cortex-A53 cores instead as per the comparison table reproduced below: That also means we now have the RK3576 specifications (some obtained from another document too): CPU Octa-core Arm processor with 4x Cortex-A72 cores at 2.2 […]

Qualcomm Snapdragon X Elite SoC benchmarks in Windows and Linux

Qualcomm unveiled the 4.3 GHz 12-core Snapdragon X Elite processor for laptops last week since some bold claims about the performance and efficiency. The company has now released benchmarks for the processor verified by third parties such as Anandtech and Notebookcheck showing the new Snapdragon processor performance is quite amazing with the Arm processor indeed matching Apple, Intel, and AMD high-end chips. What’s more is that the new SoC was tested in both Windows and Linux (using Geekbench 6.2), so in hindsight, I was wrong to say the Snapdragon X Lite would be a Windows-only processor when only seeing the DX12 listed in the specifications… Before we look into the benchmark results, we should note that Qualcomm provided two versions of the Snapdragon X Elite laptop prototype both using active cooling: “demo config A” high-performance system configured to run at an 80W TDP, and a low-power, thinner “demo config B” […]

Linux 6.6 LTS release – Highlights, Arm, RISC-V and MIPS architectures

The Linux 6.6 release has just been announced by Linus Torvalds on the Linux Kernel Mailing List (LKML): So this last week has been pretty calm, and I have absolutely no excuses to delay the v6.6 release any more, so here it is. There’s a random smattering of fixes all over, and apart from some bigger fixes to the r8152 driver, it’s all fairly small. Below is the shortlog for last week for anybody who really wants to get a flavor of the details. It’s short enough to scroll through. This obviously means that the merge window for 6.7 opens tomorrow, and I appreciate how many early pull requests I have lined up, with 40+ ready to go. That will make it a bit easier for me to deal with it, since I’ll be on the road for the first week of the merge window. Linus About two months ago, […]
