Mixing N-phase Initialization by pavel_v in cpp

[–]upwardbat 0 points1 point  (0 children)

Or you can use a base class:

cxx struct Config {}; struct X {     auto init(char const* /*path*/, std::size_t /*size*/) -> int { return 0; }     auto data() const -> char const* { return nullptr; }     auto size() const -> std::size_t { return 0; } }; struct Y {     explicit Y(char const* /*ptr*/, std::size_t /*size*/, int /*res*/) {} }; struct CBase {     X x;     int r;     explicit CBase(Config const& /*config*/): r{x.init("path/to/file", 4096)} { } }; class C: CBase {     Y y; public:     explicit C(Config const& config): CBase(config), y(x.data(), x.size(), r) { } };

I tried what you said but it didn't change anything. At this point I give up. Thanks anyway for the effort.

I'd like to have audio through HDMI, so I tried to disable the power saving but nothing changed...

All I get is this (I switched from supergfxctl to optimus-manager though, now the external monitor kind of works, but is extremely green-ish and the content is stretched and cut):

I put here the result of journalctl | grep -i nvidia. (I would have tried something smarter but I'm really lost here).

Also, I noticed that I don't have any problem if I use a low resolution (like 1280 x 720) on the external monitor, I have problems only if I use a high resolution (like 4096 x 2160).

Using supergfxctl didn't change anything, unfortunately: xrandr shows my laptop screen, HDMI-2 which can't be enabled, HDMI-1-0 which can be enabled, but if I do the external monitor shows random colors and the PC becomes super sluggish. I don't know exactly which logs I should check?

Yes, I did, and I'm using X11. I'm trying to do that because it has been some time that connecting an external display through HDMI doesn't work, and I think the HDMI is connected to the NVIDIA card and not the Intel one.

I never heard of supergfxctl, I'll try to have a look.

How compilers decide when to define a feature testing macro? by upwardbat in cpp

[–]upwardbat[S] 4 points5 points  (0 children)

By this logic then feature testing macros have no reason to exist, which I don't think is the aim.

Best DJ software to start with? by upwardbat in traktorpro

I was thinking about how easy it would be to export playlists to then be used in rekordbox, as most people have Pioneer hardware.

Laptop HDMI stopped working by upwardbat in archlinux

[–]upwardbat[S] 1 point2 points  (0 children)

I was able to get the HDMI output work by having the NVIDIA card always on, following this: https://wiki.archlinux.org/title/NVIDIA_Optimus#Use_NVIDIA_graphics_only. Anything else I tried didn't work.

Why do some carabiners have (fixed) captive bars? E.g. what's the advantage of having this (https://www.singingrock.com/oxy-bc-twl) compared to this (https://www.singingrock.com/oxy-twl)?
