Eric has an old HP laptop that was lagging and slowing down. He replaced the hard drive with an SSD, but it still lags. Leo says it's possible that if Eric reinstalled a backup of Windows, that there's malware or some corrupted drivers that is the original cause of the lag. The best thing to do is install a fresh copy of Windows and start all over. That means backing up data, then format the drive, and installing Windows from a known, good source. NOT a backup. Then restore programs and data and see if that works.
Paul has an HP Stream, and he can't update Windows 10. Leo says that's because there's no real storage on it, with a 32GB hard drive. They want to compete with Chromebooks, but people can't do anything with them. As such, you can't really update them. You could install Linux on it. Leo recommends Linux MINT; it uses Ubuntu. There's also PopOS by System76 and Manjaro.
If you're going to be multitasking with your laptop or desktop, it is best to boost RAM as high as you can afford. If you can, upgrade the random-access memory on your existing machine or choose the highest sensible option when buying a new computer. With more memory, you can have more tabs open while browsing, you can edit larger files, etc. 4GB is the minimum for Windows 10, but it will probably result in frustration eventually. Linux actually runs better with a small amount of RAM, alternatively. Also, don't forget to replace a spinning drive with an SSD.
Joey has a PC running PopOS Linux but he wants to learn more about the secrets of the system. Leo says that there are books, but generally, it's through communities that you learn. REDDIT has many good subreddits. Reddit.com/r/linux is the definitive subreddit for it. Also, the Pop_OS subreddit would be good. Reddit.com/r/pop_os. There are also Linux and PopOS communities on Discord. That would be good too.
Guy recently put a new hard drive in his computer and he put Linux on it. But now when he tries to print he'll also get several additional pages printed out for no reason. Leo says that Linux uses an open-source printer driver called CUPS and it's printing out an error code that it doesn't understand. It's probably due to CUPS using a printer driver that is close, but not exact to the printer. Try and see if the printer manufacturer has a Linux driver. That could help. Or see if he can use a different HP driver since HP uses PCL, which is good on Linux. Give it a shot, paper is cheap.
William is blind and wants to know more about accessibility with Linux. He believes that many tools are built with the assumption of what he needs, not what he really needs. The tech world has also taken away much of the tactile nature of computing that William could benefit from.
Franklin wants to know what CUDA is in a video card and can he use it with Linux? Leo says that CUDA is a performance codec that will help higher resolution video perform at various frame rates and resolutions. The key is to make sure he's using the proprietary NVIDIA drivers for the best results. If he's using Linux, though, it's possible he won't get CUDA support, especially with Linux drivers. He could also make sure that he has OpenCL drivers as well.
Nathan recently created a dual boot PC using Windows and Majaro Linux. But now his bandwidth speed on that PC is really slow compared to his other devices. Leo says that if the slowdown is evident on both Linux and Windows, then that points to a potential hardware issue. Leo recommends to boot into Windows and go into the Device Manager to make sure the PC is using the proper drivers. They should be by Intel. He can also do a Linux LSHW (list hardware) command, or LSPCI command which will show what ethernet and Internet commands are being used.
Tom's old Acer computer hard drive died recently. Would it make a good media server if he replaced the hard drive? Leo says that sure, but try booting from a USB key first just to see if everything is working. You'll have to go into the BIOS/Setup and change the boot order. Then burn a copy of Linux to a thumb drive and boot it up. You could also do it with a Windows Media Creation Tool. Once you've verified that the computer is intact and OK, then you can replace the hard drive and turn it into a media server.
Quincy likes using MINT Linux on his old Dell Latitude laptop because it looks a lot like Windows. But the video has been glitching. Leo says that Mint may have chosen the wrong driver when he installed it. Linux uses video drivers made mostly by enthusiasts, and relying on the motherboard graphics is the easiest to get drivers for. But he may want to check the video card manufacturer to see if they have a Linux driver available. Try googling the model laptop with Linux and see what drivers pop up, and who has solved that issue.
