[xcrysden] 回复: xcrysden 1.6.2 can't startup

[John Yang]

Hi Tone,

After xrandr --dpi 96, I still got:
dimensions:    3000x2000 pixels (0x0 millimeters)
resolution:    -2147483648x-2147483648 dots per inch

Please look at the resolution, a very funny value.

I start to suspect it is because I’m using the VMware rather than an physical monitor. Everytime I maximize, full screen the guest system CentOS 8, the monitor does changes. And I don’t even have a monitor.conf in /etc/X11/xorg.conf.d    .   Very strange.

Anyway, thanks for your help.

This appears like a system problem: it seems your X cannot convert
"millimeter" units to pixels. Check with xdpyinfo, i.e.:

xdpyinfo | grep dimensions

I get:
  dimensions:    1680x1050 pixels (444x277 millimeters)

but I suppose you will get something like:
  dimensions:    3000x2000 pixels (0x0 millimeters)

You can solve this with:

xrandr --dpi 96


The alternative is that you modify the xcrysden code and replace the
millimeter specs with the pixel specs. For the particular error you
got, edit the Tcl/xcInit.tcl file and change "0m" to "0" in the line:

"pack .title.f.l .title.f.l2 -side top -fill both -padx 0m -pady 0m"


Best regards, Tone
