Editor to share with you what are the common problems in Linux, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Sometimes you will encounter some difficult and complicated problems, and the monitoring plug-in can not immediately identify the root cause of the problem. At this point, you need to log on to the server to further analyze the root causes of the problem. Then the analysis of the problem requires the accumulation of certain technical experience, and some problems involve a wide range of areas in order to locate the problem.

1. Wifi driver (especially Broadcom chip)

Generally speaking, Wifi drivers, especially Broadcom wireless network cards, are still one of the biggest technical problems facing Linux. On LQ, there were hundreds of posts discussing the topic in 2016, as well as countless other places. There are dozens of Broadcom wireless network cards available on the market, but describing specific troubleshooting details for each release is beyond the scope of one article, but the basic troubleshooting steps are the same:

Identify the PCI ID by using the lspci command to determine which Broadcom card to use, determine whether the card is supported by the distribution, and if so, find the correct way to make the network card work.

For example, if you have a 14e4:4315 PCI ID card and the system is Ubuntu, you should know that the BCM4312 card can be driven by installing the inline code block firmware-b43-installer package. Another option is to study the available WiFi cards before buying to make sure your distribution fully supports it.

two。 Printer drivers (especially Canon and Lexmark)

Printers are often problematic, and Canon and Lexmark have been repeatedly mentioned to encounter such problems. If you want to buy a new printer, study compatibility before you buy it. However, if you migrate from another operating system, this may not be a choice. If you are doing research, the OpenPrinting database and the official support channels for your distribution are the two best starting points. Please note that you should make sure that all the features of the device are fully compatible, especially if it is a multi-functional product. A common complaint about Canon printers is that drivers are usually only available on websites that are non-English or even hard to find. If you are buying a new printer, please study the compatibility before you buy it.

3. Video card

Graphics cards are a delicate topic, because graphics cards on Linux can be very simple and intuitive to use right out of the box. The problems that arise are: video card accelerator / 3D acceleration; the latest graphics cards and the latest display technologies, such as NVIDIA Optimus and ATI dynamic GPU switching; installation and stability of proprietary drivers; energy efficiency management; and reliable hang and restore. If you're not a gamer, there's no other need for high-end graphics, and you're not using a laptop, then you probably don't have to worry about it. If you are looking for a new laptop, be sure to study compatibility before you buy it. If you are a gamer or need the most advanced graphics features, you need to know exactly what your needs are, and then start your research. Fortunately, the situation is improving, Wayland is starting to solve the problem, and things should get better in 2017.

4. Sound card

Third, for simple configuration, the sound card is very easy to set up and can run reliably on the Linux. Once you buy professional products such as echo cancellation, audio routing, unified mixing, and other complex configurations, it can quickly go from bad to worse. My advice is that if you need high-end real-time audio, please use a dedicated audio-related distribution.

5. Installation

With this all-inclusive classification, this article is almost guaranteed to be of high quality. In other words, to be fair, I didn't know that Linux had a general installation problem. The vast majority of installations went as expected. Linux supports a variety of hardware, and there may be almost unlimited combinations of hardware on the installed Linux machine, which inevitably leads to exceptions in certain cases. End users also rarely install other systems like Mac OS or Windows, as they are pre-installed with new devices. The vast majority of installations went as expected.

The future is bright.

Other issues often mentioned include Bluetooth, suspend / restore, HiDPI and touchscreen. You may see a pattern formed here, and most of the issues mentioned in this article focus on desktop users. If you are already aware of this, it actually makes sense. Linux desktop usage is relatively low, resulting in very few tests and resources to identify and resolve related issues. As desktop usage increases, these parts can be expected to improve.

In this regard, I think it's best to mention an example that used to be raised as a question of Linux, but it's been rare lately: fonts. A few years ago, getting high-quality anti-aliased fonts was often a problem. However, with the update of modern distributions, it has become the norm.
