You can use Krita. Krita is a free sketching and painting program. It was designed for concept art, illustrations, and texture painting. You can see what features are Krita supports here. Krita is an open source software. It's available on Linux. You can check it out here.
Pinta is like PaintDotNet but is open source and multi platform. It is a simple image editor with a simpler interface than gimp. I think you can run sudo apt-get install pinta. Otherwise there's PPAs on the site or you can build from source.

Inkscape is a vector drawing package which I find useful for quick drawings and diagrams. It is in the repos and I believe it can easily be installed with sudo apt-get install inkscape (I'm on Debian, but the install command should be the same.
For posterity, I recommend KolourPaint. It's an MS Paint clone (i.e., as prior to Windows 7) from KDE, but unlike other MS Paint clones (I have tried them all) it is actually as intuitive and quick as the original. Its user interface is a lot less menu-y than Pinta, and it loads far faster than GIMP, Krita, or Inkscape.
I recently bought a graphics tablet and I want to use it for solving my math homework on laptop. The picture presents what I want. Do you know any software (better foss) which I can use to deal with math comfortably? To clarify I want the program to be simple and to allow to draw on notebook-like background with grid.
Ubuntu-based distros only: Install the latest stable release from the following unofficial PPA. In addition to amd64, it also hosts packages for ARM, PowerPC and other architectures on supported versions of Ubuntu:
If you want a drawing app, but you don't want to have to add a PPA, another alternative is Krita. Krita is digital painting software. It's geared more towards artists, but it has great support for pen input with devices like Wacom tablets.
I have xfce4-screenshooter that allows me to select part of the screen to print screen, however I would like the selection to automatically open up a very simple image editor that lets me draw circles or triangles before putting the screenshot+drawing into the clipboard.
I tried to install pinta but that wasnt a failure due to dependencies + behind a proxy. What are other simple image editors to consider? (simple as in lightweight/small/few dependencies/fast to start)
I recommend trying Flameshot ( ). It allows taking a screenshot of part of the screen, provides editing tools that allow drawing on the screenshot, and allows putting the result in the clipboard. There are tools for drawing circles, ellipses, and rectangles; unfortunately none for triangles, but they can be constructed using the line tool or drawn freehand using the pencil tool.
Is there any way to get LibreOffice Draw working? It just keeps freezing and crashing over and over again. Then if i force it to quit and open it again and try to recover anything, all progress is lost. its freezing / crashing 10+ times within an hour. its very annoying that LibreOffice Draw is so ridiculous unstable. OS: Ubuntu 20.04 LTS
In addition you may want to read the answer to this question: Lubuntu 20.04, LibreOffice 6.4.3.2. My Samsung ML 1610 printer does not print text correctly through LibreOffice. It prints graphics correctly, though it seems (sic!) totally unrelated to your issue.
Also there is no much need, because the logos are provided as SVG files.The SVG data can even be used in TikZ, e.g.: the white on orange version consists of two tags . The first draws a filled colored circle, the second puts the white elements inside.This can be easily translated to TikZ:
I would like to draw either a standard chemical structure or a stick version of it.
However, the version I have does not show the stick option only as in the online manual: I have wireframe, stick and balls, and licorice. These are not the same as stick. In particular, no double bonds are displayed.
Essentially, I need to draw saccharin (left of figure). But the liquirice version is that on the center. To note that (1) the gradient of the colour might confuse the audience at hand and (2) there are no double bonds.
The stick look from the website looks better (left).

Hi gardotd426,
We have filed a bug 3137202 internally for tracking purpose and unfortunately we were not able to recreate issue locally so far.
Can you please help to provide below information -
Welp. That looks promising. So yeah I already knew this anyway, but one monitor is 164.80 while the other is 165 even. Most settings daemons and Nvidia-settings show 165 for both but yeah xrandr has always shown 164.80 for the one monitor (even when I had an AMD GPU).
Since this occurs in both Wayland and X11, and on multiple desktop environments/window managers, and regardless of whether there is a compositor or not, meanwhile there is no such issue on Windows with both monitors set to 165Hz, memory frequency behaves normally there, this is clearly a bug in the Nvidia driver.
Not sure if this will work for anyone or not. I have found that turning HDR on and off will make the memory speed drop to about 400MHz and temps are down to 45C at idle and 0 fan speed. I am thinking it is a windows issue as after reboot I have to disable and then enable HDR again. Even if I only have HDR enabled on one monitor I had to enable and disable it after a reboot. Having HDR off and then rebooting seemed to be fine and left the memory speed at around the 400Mhz after a reboot. I am using a MSI 3090 Ventus 3x OC.

Thanks for sharing the test results.
Can you please remove parameter UseNvKmsCompositionPipeline and cinfirm power drawn.
Also requesting others to share test results with latest released driver.
Now a ROOT window is opened and the histogram is drawn but the histogram is also drawn as a png inline below the cell in the notebook. Also the ROOT window is not interactive - it has File Edit View Options Tools at the top but clicking on them does nothing. The histogram seems to be an image - clicking on it does nothing and it does not resize with the window.
ps: I can run all of the scripts in root/tutorials/pyroot on both windows and linux and root windows are correctly opened and populated. So I think it must be down to different behaviour of jupyter !? Is there something simple I am missing ?
Is there any way to get the same functionality as on Windows where a proper interactive ROOT window is opened ? I am cycling through a lot of cells making different plots and the way I currently work the histograms/graphs appear one after the other on the same canvas in the ROOT window.
I do not have an explanation why you can open and interact a window with the classic graphics from a notebook on Windows and not on Linux, but I would recommend that if you want to work with the classic fit panel you use the python or IPython prompt. Soon, we will have all these graphics in JS as well and we will support them from the notebook.
Then you get an inline png of the histogram in the notebook and a window opens which also displays the histogram. The window looks like a ROOT window and has File Edit View Options Tools at the top but nothing happens when you click on them . Also the window is not interactive - nothing happens when you click or right click on the histogram and the histogram does not resize when you resize the window.
Hello, i wanted to know if there was a specific guideline to operate with the express keys and buttons on the stylus.
I am aware that the graphical interface is glitches or something so I tried mapping the buttons to "Button 1-4" for the express keys and "Button 1-2" for the stylus, with no result whatsoever.
The commands i have done are:
xsetwacom --set "Wacom Intuos S 2 Pad pad" Button 1 "key ctrl" "key z"
xsetwacom --set "Wacom Intuos S 2 Pad pad" Button 2 "key space"
xsetwacom --set "Wacom Intuos S 2 Pen stylus" Button 2 "key ctrl"
The same menus and Express Keys can therefore perform differently depending on which program you are using; for instance, Command + T can be assigned to an Express Key with Photoshop highlighted, then again with Painter highlighted.
Now I have a XP-Pen Deco 03 Wireless Graphics Tablet without Screen . This is my favourite screen-less tablet at the moment because it has the best pen pressure and drawing experience I've had so far. I don't find the advertised red dial very useful and the wireless is "eh", but if you ignore those side features, the comfort of the pen and the control you have over the pen pressure are absolutely fantastic.
In this post I am going to talk about those applications that we use when we are making a presentation with the computer and we want to point, write or draw something in a spontaneous way. This is about the desktop annotation tools.
As far as I know, such values can only be estimated, at best. If you truly want to be as close as possible to reality when measuring power consumption, there is no way around using an actual power consumption meter.
I just want to get a rough idea for how much Watts of power is being used by my Ubuntu PC running my applications and this will help me determine whether I need to update my AC adapter (as suggested in a comment on other thread on CPU throttling).
You can calculate the estimated watt usages of parts. For example, you can look up how much power certain PC parts draw on average. Then, you calculate the sum of those numbers and there you have a rough estimation.
What I observed was that power consumption varied widely, depending on what the computer was doing. It was about 55 W. at idle and about 250 W. when doing serious number crunching. An single glance at power consumption may not give you the full picture.
Anyone who's ever attempted to use a laptop on a sunny summer day can surely tell you that direct sunlight is not your friend -- that's why we like to ride out the season in our dark basement apartments. If only there were a way to harness the sun's... 152ee80cbc
