Linux has become dangerous – one of the cores of the system can physically disable the laptop display, although not on all models

Published

The Linux kernel 6.0 was recently released and version 6.1 is scheduled to be released soon. However, many users have not switched to it yet. And, as it turned out, one of the old kernels has a problem that affects the video subsystem. It can physically damage the display. This concerns the Linux kernel 5.19.12, but in version 5.19.13 the problem was solved.

Linux has become dangerous - one of the cores of the system can physically disable the laptop display, although not on all models

The failure only affected laptops with Intel processors that were running a distribution based on the Linux 5.19.12 kernel. The problem seemed to be related to the Intel graphics driver, which caused the display to flash rapidly in white. One of the engineers who is involved in the development of the core of the system explained that it was an incorrect delay in powering up the LCD panel. Because of this, the display could fail, because it is simply not designed to work in this mode for a long time.

It is noted that the problem manifested itself on laptops, where the screens were directly connected to the integrated video core. It was also relevant for models with Nvidia Optimus and some models with Radeon graphics (if available).

It is noted that laptops with AMD processors, conventional and hybrid, are not affected by this problem. Also, the developers advised not to install the “problem” update for those who have not had time to update.

And earlier it became known about a new problem with Windows 11 22H2.

The first laptop with GeForce RTX 40. Asus ROG Zephyrus M16 new generation lit up on the Web

The first laptop with GeForce RTX 40 Asus ROG Zephyrus

The first laptop based on the GeForce RTX 40 line of graphics cards has appeared on the Web. The model is called the Asus ROG Zephyrus M16.

Judging by the photo, the new M16 looks little different from its predecessor. In particular, the same thin frames have been preserved, which not every gaming laptop can boast of. For the current model, Asus is talking about 94% display space.

The current ROG Zephyrus M16 is equipped with a Core i9-12900H CPU and offers graphics cards from RTX 3050 Ti to RTX 3080 Ti. We can expect that the new model will have approximately the same configuration, but with new CPU and GPU.

Recall that the announcement of the mobile GeForce RTX 40, as well as the Raptor Lake mobile processors, is expected at CES 2023. A laptop will probably also be presented there.

What the new AMD processor is capable of for thin and cheap laptops. Ryzen 3 7320U Benchmarks Appeared

What the new AMD processor is capable of for thin

The network has the first review of a laptop based on the AMD Mendocino processor line.

What the new AMD processor is capable of for thin and cheap laptops.  Ryzen 3 7320U Benchmarks Appeared

In this case, we are talking about the recently introduced Acer Aspire 3 A315 and APU Ryzen 3 7320U. Recall that this processor contains four Zen 2 cores with SMT support and a Radeon 610M GPU with 128 stream processors and the RDNA 2 architecture at the core.

Unfortunately, there are few tests so far. In particular, we can evaluate the performance of the processor part only by Cinebench. There is more data from PCMark, but they show about the same picture.

As you can see, in multi-threaded mode, the novelty is approximately at the level of the Core i5-1130G7. The Ryzen 7 4700U is expectedly faster due to the higher number of cores.

Much more interesting is the new iGPU Radeon 610M. It is based on the most advanced RDNA 2 architecture for AMD embedded GPUs, but has only 128 stream processors. For comparison, the Steam Deck has 512 p.p., while the Radeon 680M in the Ryzen 7 6800U already has 768 p.p.

As you can see, a fairly fresh architecture does not compensate for the meager number of computing units. As a result, in 3DMark, the Ryzen 3 7320U loses a lot to all test participants. Unfortunately, there are no solutions with similar performance among them, because even the Ryzen 7 4700U is almost twice as fast.

Thus, the gaming Ryzen 3 7320U cannot be called even with a big stretch. Of course, it is possible to play some old games, but there will be big problems with modern ones. In fact, we even have examples.

As you can see, Forza Horizon 5 can be played at 720p with the lowest graphics settings and active FidelityFX CAS technology. Skyrim works at 60 fps, but at 720p at medium settings and GTA V works in much the same way. That is, you can somehow play, but you have to sacrifice a lot.

It is worth remembering that the same Acer Aspire 3 A315 costs only $ 400, that is, the Ryzen 3 7320U feels very good in this price segment.
