And from what I've read there is no read-only switch on this SD card, correct? It's just something like a chip that plugs into a Raspberry Pi or a camera, correct? I am not exactly clear from rereading what the actual SD card is or how it's attached, and you are using file system types I know nothing about. However, if only for clarity, what I've had to do even with ext3/4 is essentially the following: 1) su - and enter root password. 2) As root navigate to /home/walter/tablet or whatever the location is where you believe you are really ON the SD card 3) Create a file using vi, save the file, make sure it's there and make sure it's owned root:root. 4) Exit the su and make sure the file is there. Unmount the SD card, remount the SD card and check that it's really there. Put the SD card in some other system where you can see the file, if possible. 5) Assuming all of that makes sense, remount the CD card, su there again, and chown the file to walter:walter or walter:user or whatever is appropriate. Make sure you can edit the file from some other terminal process. 6) As root in the su, then try to create a directory. If it's still read only then this is way above my pay grade. However if you can create the directory, which I've always been able to do as root, then chown -R the directory to your user ID. It is important to ensure that OS believes you have read/write access all the way up and down the chain so you might need to chown -R walter:walter AS ROOT from your home directory into the mount point, which if I understand, is /home/walter/tablet, so I'd be root and doing the command sitting in /home/walter. Sorry. Wish I could be more helpful but this has been a problem on my systems ever since I started using Linux 25-30 years ago and I struggle with it maybe once a year. Good luck, Mark

I don't have anything as exotic running here, but you will need amdgpu, plus (potentially) amdgpu-pro for your graphics: https://wiki.gentoo.org/wiki/AMDGPU https://wiki.gentoo.org/wiki/AMDGPU-PRO You will be able to confirm what is required in respect to firmware and kernel graphics driver components once you boot up with a liveUSB.

For microcode, flash the BIOS with the latest OEM firmware and add the corresponding AMD family firmware file in your kernel: https://wiki.gentoo.org/wiki/AMD_microcode If you boot with the latest Ubuntu it will probably load everything required; then fish around dmesg and hwinfo, lspci, lscpu, etc. for relevant drivers and firmware files. > As a somewhat tangential question, would it be worthwhile getting water > cooling in my new machine?

You could invest the money toward more RAM, (more/bigger) case fans, a better PSU, monitor, speakers, a new car, etc. :-) https://www.techreviewer.com/tech-specs/amd-7700x-tdp/ Cranking up 16 threads to 5.4 GHz will produce some heat, but compiles will complete sooner too.

I am not sure what happens in Wayland, where application windows are supposed to be isolated. I recall in earlier days the Primary selection would not work between windows, which was rather frustrating. I think at present the Plasma desktop clipboard application acts as a mediator, probably engaging Xwayland - but I am not sure. There are quite a few settings in Plasma's clipboard application to configure interoperability between Primary & Clipboard selection and can be set to save the Primary selection in the Clipboard section and its history if so desired. With my current settings I can middle click to paste a Primary selection into Konsole, but Shift+Insert which works with Xterm & friends does not work with Konsole. signature.asc Description: This is a digitally signed message part.

I've never used water. I don't have anything to drink close to my puter either. I suspect that if you got a pretty good size air CPU cooler, with a large quiet fan, you will find it pretty quiet. I have a FX-8350 right now. I can't recall the power it pulls right now but it is more than the newer CPUs. I have a CPU cooler with a 120mm fan and even at full load, I don't hear anything and I'm right next to it. I don't even hear the large case fans. Keep in mind, those case fans are 200mm fans. Some prefer water and for those who do, use water. I just don't see why newer CPUs that produce less heat would need water when air cooling works fine on CPUs that produce more heat. If you would rather avoid water, I can't imagine a good air CPU cooler with a large fan not being more than enough. I might add, I'm always scared the pump will decide to take a nap. At least with a air cooler, it will cool some even without a fan. Could prevent burning out the CPU if you shutdown quick. Maybe when I get me a new rig built I can share personal experience. ;-) Dale :-) :-)

When you highlight some text, the application asserts ownership of the primary selection, but no contents of the selection are transferred to the X server. So, the X server knows who owns the selection, but it doesn't actually store the contents anywhere. If you middle-click on a window, the X server will make a call to the owner of selection to get the selection contents and then provide that contents to the active window. When process (X client) that owns the selection exits, the selection becomes "empty" (unavailable). > The Clipboard may be stored in RAM or cache of any applications > which use this method. AFAICT, the clipboard contents is stored in the X server. When you cut/copy something, the application sends that something to the X server where it's stored. When that application exits, the clipboard contents are still there in the X server, and can still be requested by other applications who want to do a "paste". With the usual behavior, the selection and clipboard sort of overlap: When you highlight something the application asserts ownership of the primary selection, but nothing is transferred to the X server. If you then do a "copy", the application will send that highlighted text to the clipbard. If you haven't selected anything else, now you can either middle-click or paste, and you'll get the same thing. If you exit the app, then middle-click will produce nothing because there is no selection owner. But, paste will still get the "copied" data from the X server. That said, something doesn't have to be selected (in the X11 sense) to be copied into the clipboard -- but that's how most applications work first you select (in the X11 sense) something then you copy it to the clipboard. -- Grant
[gentoo-user] Graphics configuration for a Ryzen 7 7700X chip and water cooling.
Hello, Gentoo. My current rig is working well (hence the lack of posts to the list from me), but The time is coming up for me to buy a new PC, the current one being around 7 years old. It's served me well for that time, but nothing lasts forever. Also, it would be nice to be able to build clang and rust and friends somewhat faster. So I'm looking at getting an AMD Ryzen 7 7700X processor, and using its inbuilt graphics rather than buying a distinct graphics card. But in the doc on wiki.gentoo.org, I can't find any mention of inbuilt graphics; all references are to graphics _cards_. Does Gentoo support my intended processor's graphics, and if so, how do I go about identifying the needed microcode (if any) and so on? Am I missing something obvious in the wiki? As a somewhat tangential question, would it be worthwhile getting water cooling in my new machine? In particular, to reduce the noise it gives off while building large packages such as clang and rust? Or is water cooling only sensible for really heavy users such as gamers?

Primary - you select some text by holding down your left mouse button (or Shift+arrow) and you paste it with your middle button (or Shift+Insert - depending on application). 2. Secondary - some applications will autoselect text, e.g. when you click in the non-empty address bar of a browser. This can replace any selection you had in the Primary selection. It depends on the particular application. 3. Clipboard - this is the Ctrl+x/c/v MSWindows style of cut/copy/paste menu items. More details can be found in the spec here: https://specifications.freedesktop.org/clipboards-spec/clipboards-latest.txt As far as I know the Primary selection is not stored anywhere - other than within the application's memory space where the range of characters have been selected. The xserver will call for this when you middle click to paste it on another application's window. The Clipboard may be stored in RAM or cache of any applications which use this method. > P. S.

In X, the selection and the clipboard are two different "places". When you click-drag to highlight text, that goes into the selection. In X, there are actually two different selections: the primary and the secondary. By default highlighted text goes into the primary selection. Middle-clicking shoves the contents of the primary selection into stdin for whatever window is selected. When you do "cut" or "copy" something, it goes into the clipboard. When you "paste" it comes from the clipboard. xclip can access (read or write) all three (primary selection, secondary selection, and clipboard). https://unix.stackexchange.com/questions/139191/whats-the-difference-between-primary-selection-and-clipboard-buffer https://superuser.com/questions/90257/what-is-the-difference-between-the-x-clipboards https://www.reddit.com/r/linux/comments/mgr0v/til_x11_has_three_clipboards/ -- Grant

Well, since it works, something is acting as a clipboard. It doesn't seem to be xclip in my case.

I wanted to avoid that. Bitwarden is a awesome tool. It's like LastPasss but open source. When LastPass got bought and started limiting basic features, I switched to Bitwarden. Honestly, I wish I had started with Bitwarden to begin with. I like my passwords to have all sorts of characters in as random a order as possible. Most all password tools do a good job of this. The thing I like about the method I posted, I can control exactly what characters are used, individually. I had a website once that allowed some characters, like above the number keys on older keyboards, but didn't allow a few odd ones. LastPass and Bitwarden have the option to turn them off or on as a set but not individually. Luckily that website wasn't something sensitive like a bank or anything but still, some websites do limit what can be used and some are a bit weird. With the command I use, I can easily, in a one time way, leave out anything that I need to but leave the rest. >> […] >> Now that I have a password, how do I keep track of them?

On GPT labelled disks I make use both of the Partition Type UUID and the Partition Name. A quick glance at the gdisk output and if need be its 'i' option has saved my day from formatting the wrong partition more than once! Iirc from the days of kernel 1.3 and 2.x, the partition type is not used - at all - by linux itself. Dunno about other OSs. As you pointed out, though, it is used by other tools, which use it to identify what the partition is *supposed* to be used for. For example, auto-assemble with raid. I'm not sure, but for example I think swap will quite happily let you "mount" a non-swap partiton with swap-on. You can format an allegedly DOS or NTFS partition with ext, and linux won't care ...
