海外TECH	DEV Community	Moving from classic Linux distro to ChromeOS Flex? Here was what I found <🪲>	https://dev.to/hunghvu/moving-from-classic-linux-distro-to-chromeos-flex-here-was-what-i-found--eek	Moving from classic Linux distro to ChromeOS Flex Here was what I found lt 🪲 gt I have never been a Linux guru but as a casual user I love playing around with the operating system from time to time At one point I decided that Pop OS or PopOS is a stopping point after a long distro hopping journey It s a great all in one package with several core features ready to go out of the box Desktop customization dedicated GPU supports Bluetooth codec supports and whatnot you name it I m satisfied with PopOS and I still do but a question eventually arose When coming to laptop usage of my time spends on the browser I boot up the laptop open Firefox search the web consume media and write articles like what you are reading now For other more intensive tasks like gaming coding or so my PC is responsible for them Do I need a full fledged highly customizable operating system for the laptop Probably not so ChromeOS came to my mind In July Google announced a general availability for ChromeOS Flex formerly CloudReady a version that can be installed on non Chromebook devices any computer in other words In a sense ChromeOS Flex is bleeding edge so it is expected to be somewhat unstable at the beginning and I decided to wait until early to try it out and here I am Why did ChromeOS come to my mind MinimalismChromeOS sacrifices lots of customizability but provides a decent set of Google applications out of the box Chrome is in the name of the OS itself so that alone covers of my usage Considering I have been working with different IT systems daily I suppose having to tweak some Linux configurations outside of work hours is not that desirable Don t get me wrong playing around with technology has always been my hobby but there is a line for when I just need to get things done and ChromeOS provides that simple and minimalistic experience That said Linux on ChromeOS or Crostini is there so I can always fire up the Linux environment if needed LightweightThe minimalistic approach inherently means no bloatware comes with ChromeOS It consumes about GB of storage and GB of RAM out of the box Nothing spectacular though as PopOS is relatively the same Both ChromeOS and Linux blow Windows out of water because Microsoft somehow makes their OS consumes more than GB and storage and around GB of ram with a fresh installation Technically this resource consumption is negligible to my laptop specification AMD Ryzen U CPU Solidigm P Plus TB SSD and GB of RAM but it is always better to remove those data harvesting programs when possible SecurityWhen considering a fresh installation ChromeOS is arguably more secure than PopOS or other Linux distros Minimalism greatly reduces the attack surface and ChromeOS was designed with security in mind using sandboxing and limited user write access I m by no means an expert on cybersecurity matters but there are lots of resources online regarding this topic and Security in Chrome OS is an example And my first try Well it was worse than I expectedLiving on the edge is nothing new to me eventually things will work out That is assuming the fundamentals are satisfied at least to a certain degree The stable beta and canary versions are and respectively at the time of writing In my case I tried out ChromeOS Flex using all those versions on three different laptop models from Dell HP and Asus and all exhibited breaking bugs in one way or another What were they then Network chipset compatibilityAt the moment ChromeOS Flex does not support Intel AX and Mediatek MT wireless modules Unfortunately two of my laptops have these so I could not even start the OS installation process because ChromeOS Flex requires Internet to set up That said these are documented in ChromeOS Flex Help Known Issues so it is acceptable to me However being a PC hobbyist I have a plethora of computer components lying around so I decided to try other modules which yielded the following results Intel AC unknown revision RecognizedIntel AC unknown revision Bluetooth was recognized but no Wi FiIntel AX unknown revision RecognizedRealtek wireless module missing label unknown model UnrecognizedRealtek RTL USB to Gbe ethernet Rev was recognized while rev was a hit or miss might be due to USB implementation These are widely used wireless chipset and has long been supported in the Linux mainline kernel Clearly ChromeOS Flex needs to address these somehow Other miscellaneous hardware compatibilitiesUnlike network chipset which has only a few big players on the market such as Intel Mediatek Qualcomm and Broadcom other components of the laptops are from more obscure providers and have a lot of variations Using the PopOS s latest version kernel v at the moment there are still certain compatibility issues so I suppose it is understandable for ChromeOS Flex to stay behind in this aspect For example The touch function of a laptop screen did not work during an initial OS installation but is fine after getting to the desktop Touchpad meanwhile worked in the OS installation phase but became unusable after getting to the desktop There were also times the touchpad worked fine from start to finish but got disabled in a lock screen Generally said it was a hit or miss Speakers had the same issue as the touchpad The fingerprint was completely not supported on the three laptops I tried No tablet mode detection when the screen passed a degrees angle e g no rotation no auto on screen keyboard Somewhat lackluster in user experienceAlthough using a minimal OS is my goal ChromeOS Flex is missing certain features that reduce my overall experience They are not breaking deals though but worth to be mentioned For example Chrome tabs do not close after the browser exits and there is no option to decide whether to keep tabs between sessions Apparently ChromeOS Flex simply does not support this and the user must right click on a browser tab then choose to close other tabs before exiting the browser It is an oversight in my opinion Website scroll speed is very inconsistent as in the acceleration kept jumping around It seems this was once reported in Chromium Issue but it is not viewable anymore ChromeOS Flex has worse settings than PopOS such as no main monitor resolution no time to sleep no sleep button and no Bluetooth codec adjustment No trivial way to enable the tablet mode which is commonly used when a laptop is a in type The workaround I found was to enable the ASH shortcut flag in Chrome then press CTRL ALT SHIFT T to enter and exit the tablet mode There is a disassociation between mouse action and touch gestures in tablet mode For example swiping right means return but it is only doable with a touch gesture not with a mouse cursor Even inside the tablet mode the on screen keyboard does not automatically open when typing and must be manually turned on and off in Settings This creates a blockage when a user switches between desktop and tablet mode frequently Non standard way to enable an extra keyboard for special characters Keyboards in other operating systems tend to reserve SHIFT for capitalization or expand options of one key and an extra keyboard can be accessed using a special button at the corner Meanwhile SHIFT is used to switch keyboard types in ChromeOS Flex The list goes on but again not that big of a deal Then I found a serious issue with ChromeOS Flex which can potentially harm my laptops in the long run and that was Completely broken sleep systemUsing a laptop I rarely shut down the machine rather sleep is my usual choice Why It is simply about convenience what is better than just opening the lid and all your application is there in their previous state And yet Chrome OS completely broke my laptop s sleep functionality There are three types of breaking bugs The laptop cannot wake up from sleep I m away from the keyboard or close the lid and the laptop goes to sleep screen off keyboard led off fan spin down no battery drain However when trying to turn it on the fan spins and the keyboard led lights up but no screen In this case the screen is completely off no backlight and HDMI output does not provide a display signal Only forcing the shutdown by pressing the power button can exit this state The laptop cannot go to the sleep state I m closing the lid and the laptop does not go to sleep screen off keyboard led off fan either spins down or keeps rotating battery drains even faster than usual The laptop is unresponsive after waking up On one of my laptops that uses HDD when the laptop goes to sleep as expected and wakes up It is normal in the lock screen but after singing the user inputs keystroke mouse movement are delayed for more than minute which effectively renders the laptop unusable I have to force shutdown with the power button to exit this state This persists through HDD replacement but the problem disappears when using an SSD Here is the best part these problems randomly happen but at a very high frequency likely more than of the time I consider them harmful to my system because repetitive behaviors like force shutting down unsafe shutdown and battery drain can potentially corrupt OS or even degrade the hardware over time Are these isolated issues that only happen to my laptops Maybe but I could not identify the root cause Here was what I found in the log for type one wall of text with my educated guess on their meaning In this scenario I opened the laptop and sign in then let it stay there not open any program or do anything until the sleep kicks in Starting to go sleep T Z INFO powerd suspend delay controller cc Got notification that delay shill is ready for

Lightweight security and minimalism these aspects can bring your device a new life be it a powerful machine or one that has been in storage for years Feature wise it is expected to not be comparable to a full fledge operating system such as PopOS and that is completely fine to me Without the very broken sleep functionality I may have continued my journey with ChromeOS Flex and its ecosystem but for now I have to postpone the plan I wonder a year from now what will Chrome OS Flex become This article was originally published at 🪱ChromeOS Flex have I just opened a can of worms If you find my
