This means users who want to improve their performance by lowering the link speed setting (e.g. from wan to adsl) will not get the image compression nx thinks is best for the link speed but the one that is pre-defined by x2goclient, which is always 16m-jpeg-9. So they will not benefit from the best performance. See https://github.com/ArcticaProject/nx-libs/issues/802 for a description of the defaults: ----------------------------------------------- There are some high level compression modes, too, that will map to one from the list above: - "lossy" will map to "16m-jpeg" - "lossless" will map to "16m-rle-9" for link=lan and "16m-bitmap" for all other link types. - "adaptive" will choose lossy or lossless, depending on the characteristics of the image If no pack method is provided it will be set automatically from the link parameter: - modem: adaptive-3 - isdn: adaptive-5 - adsl: adaptive-7 - wan: adaptive-9 - lan: adaptive-9 -----------------------------------------------
