Not sure why that is - I frequently use a remote desktop with my headless Raspberry Pi and haven't seen that problem. Are you using X over SSH? (I just enable XDMCP on my LAN and use Xephyr to connect. If someone can sniff those packets I've got bigger problems to worry about than un-encrypted network traffic!). You can't (yet) easily change the font size but you can make the window bigger by modifying the following lines in x11-calc.h. I added this feature so I could resize the windows to fit the display when using one of the Pi touch screens. If you want to mess with the font _names_ they are defined in x11-calc-font.h. Code:
Nice to know to compiles with unstable! I'm not sure how things work on a MacOS but if you have the X headers installed you should be able to compile it natively.. Mike T. HP21, HP25, HP32E, HP33C, HP34C, HP10C, HP11C, HP12C, HP32S, HP22S |

RE: Yet another HP simulator (using C + X11)
thanks! Yes, X over ssh; my server doesn't allow any other sort of login.
I'll give those compiles a try, thanks again. Cambridge, UK 41CL/DM41X 12/15C/16C DM15/16 17B/II/II+ 28S 42S/DM42 32SII 48GX 50g 35s WP34S PrimeG2 WP43S/pilot/C47 Casio, Rockwell 18R |

RE: Yet another HP simulator (using C + X11)
Quite a lot more work needed (as the classic machines have slightly different opcodes) but I was wondering what the HP45 fans make of this:

Looks good!
Seems to answer the question: What would an HP-45 look like if it were a Woodstock? --Bob Prosperi |

For a real 45-like appearance, I suggest these tweaks: -Smaller buttons with more space between them -The 4 math operator keys should be half-width (nearly square) -In several places "-" should be arrow keys, "->" -y^x, e^x and 10^x powers should be higher -Label for [shift] [Rv] should have a bar above the x With such changes, it will be much closed to real 45 in appearance. --Bob Prosperi |

I just tried building and running the latest from GitHub in a VM running Ubuntu 14.04, and I found that it was dropping mouse events as well, and also just being unbearably sluggish overall. I noticed that while the app was running, compiz was running at over 100% CPU, and xorg was using another 40% or so. Compiz pegging a core could explain the dropped events. Note that this version does include the -std=gnu99 option that was mentioned earlier... it also includes -no-pie in src/makefile, which I had to remove because it was not recognized, and causing compilation to fail. |

Thomas, If would he helpful to know what VM host you have and which desktop you were using? Was the simulator using 100% CPU all the time? If it was then that suggests that it is using a default busy loop rather then an dependent sleep() function. If you send me a private message with the output of 'dpkg --get-selections' that would be useful (alternatively create an issue on github https://github.com/mike632t/x11-calc/blo...em-reports and attach it there). I'll see if I can set up an Ubuntu 14.04 VM in the meantime. Having seen a similar issue on the Raspberry Pi there I suspect there may be a problem drawing the X11 primitives when hardware acceleration is enabled. It is worth trying to reproduce the problem but I'm not sure I can do much about it! Mike T. HP21, HP25, HP32E, HP33C, HP34C, HP10C, HP11C, HP12C, HP32S, HP22S |

Unfortunately I really can't do a lot about the text without a custom font (I know there is a suitable true fype font somewhere but I can't use it as I can only use an X11 bitmap font). I've made the math function keys narrower, but left the others unchanged to keep the buttons as big as possible so they are easier to use with a touch screen. Mike T.

Pretty much, yes, but note that it's not the simulator itself that's using all that CPU time: Code: top - 20:01:47 up 10 min, 3 users, load average: 1.02, 0.61, 0.38 (12-26-2021 04:13 PM)Mike T.

RE: Yet another HP simulator (using C + X11)
For anyone that is interested I've just pushed an update to the unstable branch here:
https://github.com/mike632t/x11-calc With the help and encouragement of others of this forum I've somehow managed to add a simulation of the NUT processor and so I've been able to add the Voyager series to my virtual collection...
