Sometimes the EDID from the monitor simply cannot be reached, either because it isn't there (such as in the case of some really old monitors) or some intermediary device like a KVM switcher is corrupting it or filtering it out. Problem: Incorrect Resolution when no EDID available such as from old monitor or a KVM device

In Karmic for Intel Graphics and Lucid for ATI and NVIDIA, the logic for setting up monitor resolutions moved from the X server to the kernel, however in some cases the quirks or other specialized logic in the X server has not been copied over. The X server includes mechanisms, called 'quirks', for working around these problems and fill in missing data where appropriate. For instance, it may misreport things or omit capabilities (like VESA modes). During startup or when a monitor is hotplugged, the X server queries this data from the monitor and uses it to set a resolution.ĭue to variances in how the EDID standard is implemented by different hardware manufacturers, it cannot always be 100% trusted. For procedures to troubleshoot resolution problems, read on.Ĭomputer monitors contain a small binary packet of information called Extended Display Information Data (EDID), which describes the monitor's size, modelines, etc. Even so, it can still get it wrong from time to time, for various reasons.įor help on manually configuring screen resolutions, please see X/Config/Resolution. Over the years, Xorg has gotten much better at automatically detecting and configuring monitor resolutions. Problem: Resolution with Intel graphics was correct in Intrepid/Jaunty/Karmic (with no nf configuration) but is limited in Lucid.Problem: Resolution with Intel graphics was correct in Intrepid or Jaunty (with no nf configuration) but is limited in Karmic.Problem: Wrong resolutions, refresh rates, or monitor specs.Problem: Autodetection results in reduced resolutions available.Problem: The LCD's maximum resolution is detected automatically, but lower resolutions are not available.Problem: Incorrect Resolution when no EDID available such as from old monitor or a KVM device.

This forum is useless except for the most basic issues people are having, anything that's an actual bug or actual issues no one seems to know how to fix or don't care.Īt least be real human beings with us and level with us instead of posting these robot-like polite PR answers. I'm sorry, there's no way you guys can go through your day thinking any of your responses actually helps users. You're not real tech support, you're not real moderators, you're just people doing the bare minimum to make this forum seem active so Spotify can say they're listening to user feedback when they obviously aren't. Seriously, as the OP said, every single one of you posting this overly polite PR tech support bot responses aren't helping, you're just blatantly adding to the enshittification of this service. You guys should be ashamed of yourselves for even calling your comments help, and more so ashamed to have marked this as 'Solved.'

How can we actually make this a bug report and not just arbitrary copy and paste of basic troubleshooting tips or telling us to completely uninstall and reinstall? App opens on the wrong screen EVERY TIME [dual mon.
